Which of the following transport processes always requires metabolic energy?
A)diffusion
B)carrier-mediated transport
C)vesicular transport
D)freely permeable
E)impermeable

Question

Quizplus · Accepted Answer

Vesicular transport always requires metabolic energy because it involves the formation and movement of vesicles, which requires ATP. Diffusion and freely permeable do not require metabolic energy as they involve the movement of molecules down their concentration gradient. Carrier-mediated transport may or may not require metabolic energy depending on the specific carrier involved. Impermeable does not involve transport.
