網頁Active transport is the movement of molecules against their concentration gradient, using specialised carrier proteins and energy in the form of adenosine triphosphate ( ATP). This ATP is generated from cellular metabolism and is needed to change the conformational shape of the carrier proteins. 網頁2024年3月6日 · The transporter expends about one fifth of the ATP energy of animal cells. The cycle of action occurs as follows: Pump binds ATP followed by binding of 3 Na+ ions from cytoplasm of cell ATP hydrolysis results in phosphorylation of aspartate residue of pump. ADP is released
網頁3 sodium ions are pumped out of the cell while 2 potassium ions are pumped in, which sets up a gradient across the cell membrane for both ions. Secondary active transport does …
