Question

Explain active and passive transport brainly

Answer 1

Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes. Active transport is the movement of moleculesor ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required.

Answer 2

Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required. Passive transport is the movement of molecules or ions from an area of higher to lower concentration.
