Active transport

Vedclass · Answer

(C) Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration (i.e.,against the concentration gradient).This process requires energy in the form of $ATP$ and specific membrane proteins (pumps).In contrast,simple diffusion,facilitated diffusion,and passive transport occur along the concentration gradient and do not require metabolic energy.

Transport against the concentration gradient is known as:
