This pocket forms around the contents to be taken into the cell. Facilitated diffusion uses both gated channel proteins and carrier proteins in transport. What is primary and secondary active transport in cells? There are three types of these proteins or transporters: uniporters, symporters, and antiporters. Secondary Active Transport: An electrochemical gradient, created by primary active transport, can move other substances against their concentration gradients, a process called co-transport or secondary active transport. Active transport is a very important process. Secondary active transport describes the movement of material that is due to the electrochemical gradient established by primary active transport that does not directly require ATP. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required. a carrier protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell and animals have this. This process is not affected by the level of oxygen content.
