Explanation:
A membrane pump is a protein embedded within the cellular membrane which helps the cell transport molecules into and out of the cell. The proteins help the cellular membrane's job of being semi-permeable (allowing certain things in and out). Some molecules cannot travel directly through the cellular membrane (ions, large polar molecules) and have to rely on these proteins to get through the membrane. There are two types, channel and carrier protein pumps. Channel proteins allow for simple passive diffusion where as carrier proteins can allow for active transport as they shape/conform in regards to the molecule they are transporting. Both pumps are specific in what they transport.
