Pumps used in active transport
WebActive transport of small molecular-sized materials uses integral proteins in the cell membrane to move the materials. These proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action. In co-transport (or secondary active transport), energy from primary transport can ... WebCarrier Proteins for Active Transport. An important membrane adaption for active transport is the presence of specific carrier proteins or pumps to facilitate movement: there are three types of these proteins or transporters ().A uniporter carries one specific ion or molecule. A symporter carries two different ions or molecules, both in the same direction.
