In which process do some macromolecules get assembled from smaller components and other macromolecules get degraded to yield energy?

Answers

Answer:

Digestion including hydrolysis

Explanation:

In the process of digestion, bigger food molecules are broken down into smaller macro molecules. These macro-molecules in later stage are absorbed or accumulated by cell and further broken down to release energy. It is during the process of hydrolysis,  

Where big macro-molecules are broken into smaller polymers and further into monomers thereby releasing energy. This chemical process is assisted by an enzyme in the presence of water molecules.  

Put the following events in the correct order. Rank the options below. a. A water-soluble hormone binds with a membrane-bound receptor.
b. Open choices for matching Enzymes that were already present are activated.
c. Enzymes that were already present are activated.
d. Open choices for matching cAMP molecules are synthesized. cAMP molecules are synthesized.
e. Open choices for matching G proteins are activated.

Answers

Answer:

a- water-soluble hormone binds with a membrane-bound receptor.

e. G proteins are activated.

b.  Enzymes that were already present are activated.

d. cAMP molecules are synthesized.

Final answer:

The correct order of events when a water-soluble hormone binds to a cell's receptor is: hormone binds to receptor, G proteins activate, cAMP molecules are synthesized, and pre-existing enzymes are activated. This sequential process is essential for cellular communication and the resulting physiological response.

Explanation:

The sequence of events when a water-soluble hormone initiates a response inside a cell is a precise and coordinated process. The correct order of events is:

A water-soluble hormone binds with a membrane-bound receptor. This is the initial step where the hormone attaches to the receptor on the surface of the cell.

G proteins are activated. The binding of the hormone triggers a change that activates G proteins associated with the receptor.

cAMP molecules are synthesized. The activated G proteins then stimulate the enzyme adenylate cyclase to convert ATP into the second messenger cAMP.

Enzymes that were already present are activated. cAMP functions as a second messenger and activates enzymes known as protein kinases which in turn will regulate other cellular functions, often by phosphorylating other enzymes.

The membrane has open K channels, and changing extracellular K concentration results in a change in membrane potential. Changing the extracellular Na concentration does not significantly change the membrane potential. What do your results suggest about the number or state (open or closed) of Na channels in the resting membrane of a neuron?

Answers

Answer: Closed

Explanation:

At  resting membrane potential( RMP) sodium channels remained shut, this is because , previously  in depolarisation,the  voltage  gated sodium  channels  were opened for sodium to diffuse  into the Axon. However   these channels closed  after reaching their refractory period,s.

Therefore a  change  in the extracellular concentration of sodium will not  open them

Affinity chromatography can be used to purify proteins such as growth factor receptors. The ligand of the growth factor receptor can be linked to resin, and then an extract containing membrane proteins can be poured over the resin. If a high concentration of free ligand were poured over the resin next, what would you expect to happen?

Answers

Answer:

If a high concentration of free ligand were poured over the resin next, the growth-factor receptor will be released from the resin since the excess ligand competes with ligand attached to the resin.

In affinity chromatography, adding a high concentration of free ligand would elute the protein from the column as it competes with the immobilized ligand for binding to the protein.

In affinity chromatography, a specific ligand for a protein of interest is covalently linked to an inert resin within the column. When a solution containing the protein is passed through the column, the target protein binds to the immobilized ligand due to specific affinity. If a high concentration of free ligand is poured over the resin next, one would expect the protein to be eluted from the column. This happens because the free ligand competes with the immobilized ligand for binding to the protein, reducing the affinity of the protein for the resin, allowing it to be washed out of the column.

Genetically modified foods are derived from organisms with the _____ modified in some way that does not naturally occur.

Answers

Answer:

The correct answer will be - DNA

Explanation:

The genetically modified food is the food crops produced by the modification of the genetic material or DNA of the organism.

Since the foods are produced by the modification of the genetic material which is DNA in almost all organisms therefore the foods are known as genetically modified organisms.

The modification includes the insertion and incorporation of the selected genes into organisms like resistance to stress conditions through vectors.

Thus, DNA is the correct answer.

Final answer:

Genetically modified foods come from organisms whose genomes have been artificially altered through genetic engineering, a process that includes the use of recombinant DNA technology to insert foreign genes. These genetically modified organisms (GMOs) often exhibit desirable traits such as disease resistance and improved nutritional value. Extensive testing is done to ensure their safety and minimal impact on the environment.

Explanation:

Genetically modified foods are derived from organisms with their genomes artificially altered in ways that do not naturally occur. This artificial alteration is achieved by a process called genetic engineering, involving the use of recombinant DNA technology. Organisms receive foreign DNA in the form of recombinant DNA vectors generated through molecular cloning, making them genetically modified organisms (GMOs).

Significant examples of these include transgenic plants like corn, potatoes, and tomatoes, which were among the first crop plants to be genetically engineered. These GMOs exhibit desirable traits including disease resistance, herbicide and pest resistance, and improved nutritional value. It's important to note that, since these organisms are not naturally occurring, they undergo extensive testing to assure their safety for human consumption and ecological stability.

Proteins denature at low pH. What characteristic of acidic environments interferes with protein folding?
A. The lack of protons in the solution breaks covalent bonds in the protein
B. The excess protons in the solution break covalent bonds in the protein
C. The lack of protons in the solution breaks hydrogen bonds in the protein
D. The excess protons in the solution break hydrogen bonds in the protein

Answers

Answer: D. The excess protons in the solution breaks hydrogen bonds in the protein

Explanation: When adding acid it adds protons so it messes with the charges causing them to unfold.

The characteristic that interferes with protein folding in an acidic environment is D. The excess protons in the solution break hydrogen bonds in the protein.

Proteins are chains of amino acids with side chains. They fold due to the interaction between the hydrogens, which form hydrogen bonds. The denature occurs when the chain is unfolded.

Low pH means:

There is an excess of protons.The pH is below 7.The excess of protons interacts with the hydrogens that form the hydrogen bonds. As a consequence, the protein unfolds and losses its function.

A woman with a long history of rectocele and perineal scarring from multiple episiotomies develops a rectovaginal fistula with perineal body relaxation. She has transperineal repair with perineal body reconstruction and plication of the levator muscles. What are the CPT® and ICD-10-CM codes reported for this procedure?

Answers

Answer:

N82.3

N90.89

Explanation:

In this case, the patient has a history(not current) of the rectocele

The first diagnosis is rectovaginal fistula(Alphabetic Index for Fistula/rectovaginal is N82.3).

The second diagnosis isperineal scarring(Alphabetic Index for Scar, scarring/vulva is N90.89)

Therefore, code N81.6 won't be reported since it's stands for a current rectocele

The CPT and ICD-10-CM codes for transperineal repair, perineal body reconstruction, and plication of levator muscles for a rectovaginal fistula depend on the specific clinical details and should be assigned based on current coding guidelines and manuals.

The transperineal repair with perineal body reconstruction and plication of the levator muscles in a woman with a rectovaginal fistula is a complex procedure that addresses complications arising from obstetric trauma, such as a long history of rectocele and perineal scarring from multiple episiotomies. The CPT (Current Procedural Terminology) and ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) codes for reporting these medical services are essential for billing and documentation purposes. Due to the complex nature of the procedure and the specific clinical details provided, the precise codes would depend on the individual case and the provider's clinical judgment. However, typically procedures like this could be coded under CPT codes for repair of rectocele and rectovaginal fistula and the proper ICD-10-CM codes denoting the presence of a fistula and related conditions. It would be advisable to consult the latest CPT and ICD-10-CM manuals or coding guidelines to ensure accurate coding.

In the ABO series, the gene for blood type O is , while A and B are genes, and AB is .

Answers

Answer:

Gene for blood type O is recessive

Gene for blood type A and B is dominant

Gene for blood type AB is neither dominant nor recessive but a form of co-dominance

Explanation:

In the ABO blood group,  

A and B are dominant genes, O is recessive genes.  

So the different genotype and its corresponding phenotype is as follows –  

Genotype    Phenotype

AO     A

BO     B

AB     AB

AA     A

BB     B

OO     O

Hence, the two alleles AB occur and express together. Therefore, AB blood group is an example of co-dominance.  

Blood type also varies with the presence of Rh factor. If Rh factor is present, the blood type will represented with a “+” symbol. And if Rh factor is absent, the blood type will be represented by “-“symbol.

Final answer:

Blood type O results from two recessive O alleles; blood types A and B result from dominant A or B alleles, respectively. Blood type AB exhibits codominance, where both A and B antigens are displayed on red blood cells.

Explanation:

In the ABO blood group system, the gene for blood type O is recessive, while the A and B genes are dominant, and the phenotype AB results from codominance. Individuals with blood type O must inherit two recessive O alleles, one from each parent. A person with the genotype AO will exhibit the phenotype of blood type A, while someone with the genotype BO will have blood type B. The ABO alleles demonstrate Mendelian inheritance patterns, where individuals with both an A and a B allele will have blood type AB, showing both antigens on the surface of their red blood cells because of codominance.

In eastern gray squirrels, Sciurus carolinensis, the allele for black fur (B) is dominant to the allele for gray fur (b). In a particular population of gray squirrels, 64% have black fur and 36% have gray fur. A researcher calculated the allelic frequencies to be B=0.4 and b=0.6. Five years later, the researcher returned to the location and determined the allelic frequencies within the squirrel population to be B=0.6 and b=0.4

Answers

Answer:

The correct answer is "The frequency of the B allele increased due to the selective pressures of the environment".

Explanation:

The missing part of the question is "Which of the following could best explain the increase in the frequency of the B allele in the population after five years?" at which the answer is "The frequency of the B allele increased due to the selective pressures of the environment".

In this study, the allelic frequency for black fur (B) in eastern gray squirrels Sciurus carolinensis changed from B=0.4 to B=0.6 within a lapse of five years. This increase is explained by the effect of selective pressures of the environment. For instance, is likely that new predators were more likely to detect squirrels with gray fur over black fur, or changes in the landscape benefited the black fur squirrels camouflage.

Allele frequency in a population is calculated by the division of the number of times an allele is observed by the total number of copies of all the alleles in a population.

The frequency of allele B increased due to selective pressures of the environment.

The allelic frequencies are used to calculate the number of times an allele in a population is observed. The allelic frequencies help to understand the gene flow in a population.

In the given research, the allelic frequency for Black fur is (B) changed from B = 0.4 to B = 0.6 within 5 years. The change in the allelic frequency can be due to selective pressure, such as producing offspring more than the environment can hold.

Thus, the new predator targeted the squirrels with gray fur and led to increasing the squirrels having black fur.

Thus, the allelic frequencies increased due to selective pressures in the environment.

Scarlet gilia (Ipomopsis aggregata) usually has red flowers in an inflorescence of up to 250 flowers. In certain populations in the Arizona mountains, however, the flowers range from red to pink to white. In early summer, most of the flowers were red. Six to eight weeks later, the same individual plants were still present; the flowers ranged from pink to white, and few red flowers were present. The major pollinators early in the season were two species of hummingbirds active during the day; they emigrated to lower elevations, and the major pollinator later in the season was a hawk moth (a type of moth). The hawk moth was most active at sunset and later, and it preferred light pink to white flowers after dark. When hummingbirds were present, more red flowers than white flowers produced fruit. When only hawk moths were present, more white flowers produced fruit (K. N. Paige and T. G. Whitham. 1985. Individual and population shifts in flower color by scarlet gilia: A mechanism for pollinator tracking. Science 227:315-17).
