Which of these transport mechanisms do not fit into the rest of the group listed?
A) osmosis
B) diffusion
C) ion pumps
D) passive transport
E) facilitated diffusion

Question

Quizplus · Accepted Answer

Osmosis, diffusion, passive transport, and facilitated diffusion are all forms of passive transport, meaning they do not require energy input from the cell. Ion pumps, however, are a form of active transport, as they require energy in the form of ATP to move ions against their concentration gradient. Therefore, ion pumps do not fit into the group of passive transport mechanisms.
