All of the Following Membrane Transport Mechanisms are Passive Processes

Question

All of the following membrane transport mechanisms are passive processes except
A) diffusion.
B) facilitated diffusion.
C) vesicular transport.
D) osmosis.
E) movement of water.

Accepted Answer

Vesicular transport involves the movement of large molecules or particles across membranes through the use of vesicles, which requires energy and is therefore an active process. Diffusion, facilitated diffusion, osmosis, and movement of water are all passive processes as they do not require the input of energy.
