Question

________ help stabilize the plasma membrane structure and maintain its fluidity.
A) Sterols
B) Carbohydrates
C) Phospholipids
D) Glycolipids
E) Peripheral proteins

Accepted Answer

Sterols (such as cholesterol in animal cells) help stabilize the plasma membrane by positioning themselves between the fatty acid tails of phospholipids, reducing their ability to move and therefore maintaining the membrane's fluidity at different temperatures. Carbohydrates, phospholipids, glycolipids, and peripheral proteins have other functions in the plasma membrane, but they do not directly contribute to its stability and fluidity.
