For example, primary active transport via sodium-potassium pumps is responsible for maintaining the concentration of sodium and potassium ions. Co-transport, on the other hand, is active transport, as it depends on the electrochemical gradient of ions across the cell's membrane, particularly Na +. In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated. Whereas facilitated diffusion is a passive process and does not require energy. cell - cell - Secondary active transport: In some cases the problem of forcing a substrate up its concentration gradient is solved by coupling that upward movement to the downward flow of another substrate. The electrochemical gradients set up by primary active transport store energy, which can be released as the ions move back down their gradients. Reabsorption of glucose by the renal tubule is an example of secondary active transport. Untuk menegakkan molekul terhadap tenaga bebas gred konsentrasi dibelanjakan. Main energetic transport makes use of the vitality of ATP to move a single molecule at a time throughout the cell membrane. In secondary active transport, also known as coupled transport or cotransport, energy is used to transport molecules across a membrane; however, in contrast to primary active transport, there is no direct coupling of ATP.Instead, it relies upon the electrochemical potential difference created by pumping ions in/out of the cell. Two types of active transports can be identified in a cell. Dalam sel-sel eukariotik, ini berlaku di . Secondary packaging may be removed from the item without changing the . For this reason, active transport is divided into two main categories that include primary and secondary active transport.
