question 7 of 10
which of the following structural features of phospholipid molecules affects their ability to assemble into cell membranes?
a. phospholipids are hydrophobic.
b. phospholipids have both hydrophobic and hydrophilic regions.
c. phospholipids can alternate between being hydrophobic and hydrophilic.
d. phospholipids are hydrophilic.

Explanation:

Phospholipids have a polar (hydrophilic) head and non - polar (hydrophobic) tails. This amphipathic nature allows them to self - assemble into a bilayer in an aqueous environment, with the hydrophilic heads facing the water and the hydrophobic tails away from the water, forming the basis of cell membranes.

Answer:

B. Phospholipids have both hydrophobic and hydrophilic regions.
