Energy from ATP is necessary for moving substances across membranes Group of answer choices by facilitated diffusion. by passive transport. along (down) their concentration gradient. against their concentration gradient. that are small and hydrophobic.
Bryan V.
Carrier proteins: a. mediate primary active transport. b. transport ions or molecules across the membrane without hydrolysis of ATP. c. have two classes: uniporters and symporters. d. utilize the gradient of one ion to drive the transport of another ion down its concentration gradient. e. provide translocation across the membrane only for molecules.
