Active Transport In Plasma Membrane Official

Active transport is the movement of molecules across the plasma membrane from an area of low concentration to an area of high concentration, requiring energy input. This process is essential for transporting molecules against their concentration gradient, which is necessary for maintaining proper cellular function. Active transport is different from passive transport, which involves the movement of molecules down their concentration gradient without the need for energy.

This is the direct use of metabolic energy (ATP) to transport molecules across a membrane. active transport in plasma membrane
