The Molecules That Stabilize the Cell Membrane and Prevent It

Question

The molecules that stabilize the cell membrane and prevent it from breaking easily are the
A) phospholipid molecules
B) cholesterol molecules
C) protein molecules
D) all of the above

Accepted Answer

Cholesterol molecules play a significant role in stabilizing the cell membrane by preventing it from becoming too fluid or too rigid. They help to inhibit the movement of the phospholipid molecules and maintain the proper fluidity of the membrane. While protein molecules also play a role in stabilizing the cell membrane, they primarily function as channels, transporters, and receptors rather than as structural stabilizers. Therefore, the best choice is B, cholesterol molecules.
