⭐To sustain life or for survival many substances need to be transported into or out of and between cells.
⭐Cell membranes are semipermeable which means that they have control over what molecules can or cannot pass through the cell membrane .
⭐It is the term which is used to describe the processes of moving materials through the cell membrane that requires the use of energy.
⭐ There are three main types of Active Transport that is
✨The Sodium-Potassium pump.
✨Exocytosis
✨Endocytosis.
⭐Active transport requires the assistance of a type of protein called a carrier protein that uses energy supplied by ATP.
⭐FURTHUR:--
➡Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentratioN.
⭐basically , To move substances against a concentration that requires a cell must use energy.
