Which biomolecule is most associated with the structure and function of cell membranes?
A) Polysaccharides
B) steroids
C) DNA
D) phospholipids
E) ATP

Question

Quizplus · Accepted Answer

Phospholipids are the primary building blocks of cell membranes. They have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail that give the cell membrane its characteristic structure and function. Steroids and ATP are important biomolecules, but they are not directly associated with cell membrane structure and function. Polysaccharides are also integral to the cell membrane, but they are not the most closely associated biomolecule. DNA plays a role in cell growth and replication, but it is not related to the structure of cell membranes.
