Question

Which of the following cell processes depend on the movement of membrane components and would probably not be possible if membranes were rigid, nonfluid structures?

a) cell movement
b) cell division
c) formation of intercellular junctions
d) endocytosis
e) All of these are correct.

Answer 1

These processes include cell movement, cell division, formation of intercellular junctions, and endocytosis. Therefore, the correct option is E.

Step-by-step explanation:

The movement of membrane components in cells is essential for various cell processes and would not be possible if membranes were rigid and nonfluid. These processes include cell movement, cell division, formation of intercellular junctions, and endocytosis. For example, cell movement relies on the flexibility and motion of membrane components to allow the extension and retraction of cellular protrusions like pseudopodia and flagella. Endocytosis, the process by which cells take in molecules by engulfing them in vesicles, also requires the movement of membrane components.
