B) lipids
C) sugars
D) sterols

Question

Quizplus · Accepted Answer

Eukaryotic cells add rigidity to their plasma membrane by including sterols, such as cholesterol, in the membrane. Sterols help to maintain the integrity of the membrane by reducing its fluidity, thereby increasing its rigidity. This is particularly important for cells that need to maintain a stable barrier between their internal environment and the external environment. Protein, lipids, and sugars are also important components of the plasma membrane, but they do not specifically contribute to membrane rigidity in the same way that sterols do.
