Which of these statements about carrier-mediated facilitated diffusion is true? a. It uses cellular ATP. b. It is used for cellular uptake of blood glucose. c. It is a form of active transport. d. None of these are true.
Among the membrane transporters, the channels require energy and therefore are involved in active transport. *
D. Disagree, because channels are not proteins and therefore are not involved in active tranport.
A. Agree, because channels are associated with H+-ATPase.
