Which statement accurately describes membrane phospholipids?

Question

Quizplus · Accepted Answer

Membrane phospholipids have a unique structure with a hydrophilic phosphate head group and hydrophobic fatty acid tails. This allows them to form a lipid bilayer, with the hydrophilic heads facing outward and the hydrophobic tails facing inward. This arrangement helps to maintain cellular integrity and selectively regulates the movement of molecules in and out of the cell. Option A and B are both incorrect as they describe the phospholipids as entirely hydrophobic or hydrophilic, which is not true. Option D is also incorrect as it describes the phospholipids as having hydrophobic phosphate head groups, which is not possible as phosphate groups are inherently hydrophilic.
