How is a carrier protein different from a channel protein?
A)Carrier proteins use ATP, but channel proteins do not.
B)Carrier proteins undergo conformational change so that they are open alternately to one side of the membrane or the other.
C)Transport through carrier proteins depends on concentration gradients, but transport through channel proteins does not.
D)Transport through a carrier does not depend on the random motion of molecules.
