Question

The lipid that stabilizes the membrane at extreme temperatures and is found in the hydrophobic regions of the bilayer is:

A) the polar head.
B) glycolipid.
C) glycocalyx.
D) the nonpolar tails.
E) cholesterol.

Answer 1

The lipid which stabilizes the membrane at extreme temperatures and found in “hydrophobic regions of bilayer is cholesterol”.

Answer: Option E

Explanation:

The phospho lipid bilayer is composed of two layers of hydrophobic tail and hydrophilic head in which the former is located in intracellular structure and the later is located in extracellular space of the cell.

The hydrophobic tail contains lipid called cholesterol which is involved in maintaining the stability of the cell at high temperature. When the cell experiences high temperature, the cholesterol immediately stabilizes the cell by increasing the melting point of the cell.

Answer 2

The lipid that stabilizes the membrane at extreme temperatures and is found in the hydrophobic regions of the bilayer is: the polar head. - A)
