Transport ((free)) | What Is The Difference Between Primary And Secondary Active

A membrane protein (co-transporter) couples the movement of one molecule down its gradient (releasing energy) with the movement of a different molecule against its gradient (using that energy).

Cells must constantly move molecules against their concentration gradient (from low to high concentration). This process requires energy and is called active transport . However, not all active transport is the same. The key distinction lies in where that energy comes from . A membrane protein (co-transporter) couples the movement of

A membrane protein acts as a pump. It binds to a molecule on one side of the membrane, breaks an ATP molecule to release energy, changes shape, and releases the molecule on the other side. A membrane protein (co-transporter) couples the movement of
