Which of the following statements about a typical plasma membrane is correct?a. Phospholipids are the primary component that det
nordsb [41]

Answer:

B

Explanation:

The fatty acid tails of phospholipids are hydrophobic – meaning they are ‘water-hating’. This is why they are in the middle of the bi-lipid layer of the cell membrane 'hiding' from the 'watery' environment of a cell. This poses a challenge in the diffusion of large and charged molecules across the membrane -such as sodium ions. Such molecules need transmembrane protein channels to help them cross the membrane. These are called integral proteins because they are part and parcel of the cell membrane. The cell membrane, in addition, also has glycolipids and glycoproteins on its surface that are significant in the identification of the cell by other cells.

Consider the observation that serine is the amino acid residue that can be replaced by another amino acid with the least effect
iVinArrow [24]

The question has incorrect option, however the question can be answered by the general explanation. On the basis of the general explanation the answer is as follows:

Answer:

The correct answer is - Serine has a small side chain that can fit in any relatively polar environment.

Explanation:

Serine is an amino acid that have a small side chain in comparison of other amino acid and can be replaced by another amino acid with very least effect on the structure and function of a particular protein as they can fit in any relatively polar environment.

Serine have hydroxyl group in their side chain. It is polar amino acid that can easily establish itself in any polar condition and cause least changes in protein structure and function.

Thus, the correct answer is - Serine has a small side chain that can fit in any relatively polar environment.
