Active transport: primary & secondary overview (article)

WebPumps and Transporters Pumps, also called transporters, are transmembrane proteins that actively move ions and/or solutes against a concentration or electrochemical gradient across biological membranes. Pumps generate a membrane potential by creating an electrochemical gradient across the membrane. WebCalcium ions are also used for signaling inside other cells, and similar pumps are found in the cell membrane of most cells. They constantly work to reduce the amount of calcium to very low levels, preparing the cell. Then, at a moment's notice, the cell can allow a flood of calcium to enter, spreading the signal to all corners.
