Phospholipid bilayer with equal amounts of saturated and unsaturated fatty acids displays a specific permeability to glucose. what effect will increasing the proportion of unsaturated fatty acids in the bilayer have on the membrane's permeability to glucose

Answers

Answer 1

Increasing unsaturated fatty acids in the phospholipid bilayer would increase the permeability of glucose. This is due to the kinks that are on unsaturated fatty acids that would cause the membrane to shift and move more than if it were to have saturated fatty acids which are more stable and make the membrane less permeable.

DNA and RNA are made up of monomers called nucleotides. - DNA and RNA both have 3 nitrogenous bases: Adenine, Cytosine and Guanine. - DNA and RNA both have a phosphate groups in their nucleotides. Sometimes called phosphoric acid

Structurally, DNA and RNA are nearly identical. However, there are fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine. DNA is usually double-stranded (double helix) and most cellular RNA is single-stranded (single helix). In DNA, the common organic bases are adenine, guanine, cytosine, and thymine. In RNA on the other hand, the common organic bases are adenine, guanine, cytosine, and uracil. Transcription is the process of converting DNA into a correlative RNA code, or in other words, making an RNA copy of a gene sequence. This copy is called a messenger RNA molecule, or mRNA. It is basically a large group of RNA molecules that transport genetic information from the DNA to the ribosomes. The mRNA does this by leaving the cell nucleus and entering the body of the cell, which is the cytoplasm. During translation, protein is assembled when the ribosomes translate the sequence in the arriving mRNA. They then bring in the appropriate amino acids needed to complete the protein synthesis. Together, transcription and translation are referred to as gene expression. RNA consists of three major types: mRNA (messenger), tRNA (transfer), and rRNA (ribosomal). As said before, mRNA serves as temporary copies of DNA information. tRNA on the other hand, are the ones that transfer the amino acids to ribosomes in order that they can be assembled into protein. Finally, there is rRNA, which has an entirely different function altogether, as a molecular component of the ribosome. In short, rRNA is essentially the cell’s main protein factory. While it does not make proteins directly, it does produce and link together assemblies of amino acids (polypeptides) that have the job of making them. * Sorry I just had a paper on this and feel like spouting a whole bunch of info

Which of the following statements describes a characteristic feature of a carrier protein in a plasma membrane?

Answers

Plasma membrane exhibits specificity for a particular type of molecule. Hence the correct option is a.

A characteristic feature of a carrier protein in a plasma membrane is its specificity for a particular type of molecule. Carrier proteins are integral membrane proteins that play a crucial role in facilitated diffusion and active transport by selectively binding to specific molecules and transporting them across the membrane. This specificity arises from the protein's unique structure and binding sites, allowing it to recognize and interact with particular substances.

Unlike channel proteins, which form pores for passive diffusion, carrier proteins undergo conformational changes to facilitate the movement of specific molecules across the membrane. This selective binding and transport make carrier proteins essential for the regulation of substance movement in and out of cells, contributing to the maintenance of cellular homeostasis. Hence the correct option is a.

In animal cell mitosis, the cleavage furrow forms during which stage of the cell cycle?

Answers

In animal cell mitosis, he cleavage furrow forms during the early anaphase of the cell cycle. It's caused by a ring of actin microfilaments, called the contractile ring. The actin filaments are both pre-existing and new. The contractile ring tightens around the cytoplasm of the cell.

Final answer:

The cleavage furrow forms during the cytokinesis stage of animal cell mitosis.

Explanation:

In animal cell mitosis, the cleavage furrow forms during the cytokinesis stage of the cell cycle.

Cytokinesis is the final stage of mitosis, where the cytoplasm divides and two daughter cells are formed. In animal cells, the cleavage furrow is formed during this stage.

The cleavage furrow is a groove that forms in the cell membrane, and it deepens until it completely separates the two daughter cells.

rigor mortise/ initial decay

Answer: Rigor mortis

Rigor mortis or postmortem stiffening is the one of the stages of the changes that occurs in the dead body. It initiates after primary flaccidity in which the body relaxes after death and stiffening starts after that. In this all muscles of the body are affected. It starts developing after two to six hours after death. It first begins in the eyelids, then on neck and jaw and finally to upper and lower parts of the body. It develops due to the accumulation of lactic acid in the body. The accomplishment of rigor mortis results in the softening or relaxation of the body which is called as secondary relaxation.
