Work Step by Step
(1) Similarity between pumps and transporters is that they both facilitate the movement of molecules or ions across the cell membrane.
(2) Difference between pumps and transporters is;
.Pumps must be powered by an outside energy source, such as ATP hydrolysis, in order to move molecules or ions against a gradient of concentration. Also move ions against their concentration gradient.
.Transporters do not require an external energy source, such as ATP, and they may move molecules or ions across the membrane according to their concentration gradient. Hence, they are passive transporters .Also move ions down their concentration gradient.
