Which of these 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 as it involves the formation of vesicles and their movement using cellular machinery. Diffusion and carrier-mediated transport can occur without additional energy, depending on the concentration gradient and availability of carriers. Freely permeable substances can move across membranes without any transporters or energy. Impermeable substances cannot cross the membrane at all.
