Joanna Q.
Facilitated diffusion and active transport both $a$. require ATP. $b$. require the use of proteins as carriers or channels. c. carry solutes in only one direction. $d$. increase without limit as the concentration gradient increases. e. depend on the solubility of the solute in lipids.
Which of the following is incorrect regarding facilitated diffusion? a. It is a passive process. b. It allows the movement of molecules from areas of low concentration to areas of high concentration. c. It may use either channel or carrier proteins. d. It allows the rapid transport of glucose across the membrane
