Which of the following processes require the use of protein carrier molecules?
A) facilitated diffusion and solute pumping
B) facilitated diffusion and vesicular transport
C) vesicular transport and osmosis
D) osmosis and filtration
E) filtration and exocytosis

Question

Quizplus · Accepted Answer

Facilitated diffusion and solute pumping require the use of protein carrier molecules to transport substances across the cell membrane. Vesicular transport involves the formation of vesicles, which do not require protein carrier molecules. Osmosis and filtration do not require protein carrier molecules, as they involve the movement of water and small solutes through channels or pores in the membrane. Exocytosis involves the expulsion of materials from the cell, which also does not require protein carrier molecules.
