What Is Active Transport In A Cell ((new)) Site

This is the direct use of energy. The protein pump breaks down ATP to get the energy needed to change shape and push a molecule across the membrane.

Without active transport, life would grind to a halt. It is responsible for: what is active transport in a cell

is the movement of molecules or ions across a cell membrane against their concentration gradient (from an area of lower concentration to an area of higher concentration). This process requires energy (usually in the form of ATP) and the involvement of specific membrane transport proteins (carrier proteins). This is the direct use of energy
