Question

question
passive transport is the spontaneous movement of substances down their concentration gradients and does not require energy. which of the following processes is not a type of passive transport?
select an answer
a. facilitated diffusion
b. simple diffusion
c. osmosis
d. exocytosis

Explanation:

Facilitated diffusion, simple diffusion, and osmosis are passive - transport processes that move substances down their concentration gradients without energy. Exocytosis is an active - transport process where cells release substances out of the cell by fusing vesicles with the cell membrane, which requires energy.

Answer:

D. exocytosis
