Question

What kind of molecule passes through the lipid bilayer of the cell membrane? A. cholestrol. B. phospholipid. C. intergral protein. D. peripheral protein.

Answer 1

Cholesterol can pass through the lipid bilayer of the cell membrane. This is due their lipophillic nature. They are non-polar and can move freely through the phospholipid bilayer, via the tails of the phospholipds.cholesterol contains four fused hydrogen and carbon rings, and its structure allows it it float in and out the membrane

Answer 2

The answer is A. In spite of the fact that it is a lipid, cholesterol looks to some extent like a phospholipid. The hydrophilic space of cholesterol is very little, comprising of a solitary hydroxyl gathering. It has been known for a considerable length of time that the expansion of cholesterol to a liquid stage bilayer diminishes its penetrability to water.
