Question

Which of the following statements regarding lipid bilayer is true?

A. The lipid bilayer is flexible and are not able to bend.
B. The hydrophobic molecules are polar and form favorable interactions with water.
C. A typical membrane lipid molecule has a hydrophilic head and are amphoteric.
D. The membrane phospholipids are nonmotile.
E.
The most abundant lipids in cell membranes are phospholipids.

Answer 1

The true statement regarding lipid bilayer is E. The most abundant lipids in cell membranes are phospholipids. The lipid bilayer is made up of two layers of phospholipid molecules, with the hydrophilic heads facing outward and the hydrophobic tails facing inward. This structure provides a barrier that separates the inside of the cell from the outside environment, while also allowing for the selective transport of molecules across the membrane.
