Active transport

Vedclass · Answer

(C) Active transport is the process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration.This process requires energy in the form of $ATP$ because it moves substances against the concentration gradient.In contrast,diffusion and facilitated diffusion are types of passive transport that move substances along the concentration gradient and do not require energy.

Transport occurs against the concentration gradient.
