Question

Which evidence BEST supports the claim that phospholipids helps the cell membrane carry out its function?



A.
The lipids in the bilayer are made of simple sugars, which enable the cell membrane to store energy for the cell.

B.
The lipids in the bilayer are saturated (straight) and unsaturated (bent), which contributes to the fluidity of the cell membrane.

C.
The lipids in the inner part of the cell membrane are water soluble, which allows materials to pass freely through the cell membrane.

D.
The lipids in the inner part of the cell membrane are attached to the cell's DNA, which helps the cell membrane to store genetic information for the cell.

Answer 1

B

Phospholipid tails that are saturated (straight) or unsaturated (bent) affect membrane fluidity. That fluidity is essential for membrane functions like protein movement, diffusion of molecules, and membrane fusion.
