The main lipid components in cellular membranes are ________.
A)glycerolphospholipids
B)fatty acids
C)steroids
D)triacylglycerols
E)waxes

Question

Quizplus · Accepted Answer

Glycerolphospholipids are the most abundant lipids in cellular membranes. They have a glycerol backbone, two fatty acid tails, and a phosphate group attached to a polar head group. These molecules form a bilayer that provides the barrier between the inside and outside of the cell.

Answer: C 
 While steroids are not as abundant in cellular membranes as glycerolphospholipids, they are still an important component. Cholesterol, a common steroid found in animal cell membranes, helps regulate membrane fluidity and stability.

Therefore, the best choices are A and C.
