Red blood cells are characterized as having an actin cytoskeleton associated with their plasma membrane. The presence of the membrane cytoskeleton MOST likely accounts for:
A)the shape of the cell.
B)enhanced gas exchange.
C)the ability of these cells to fit through narrow capillaries.
D)All of these choices are correct.

Question

Quizplus · Accepted Answer

The membrane cytoskeleton of red blood cells plays a significant role in maintaining the shape of the cell (A), which is important for their function in gas exchange. The cytoskeleton also allows the cells to deform and fit through narrow capillaries (C), which is essential for their circulation throughout the body. Therefore, all of these choices are correct (D).
