Web7 aug. 2024 · The flow of protons through the ATPase allows the enzyme to synthesize ATP. The exact amount of ATP that is generated by this process has not been clearly established, but current thought indicates that for each pair of electrons that enters the chain from NADH, 10 protons are pumped out of the mitochondria. WebAs the electrons arrive on complex I, the complex immediately goes through a series of redox (reduction and oxidation) reactions. These reactions create a proton pump within complex I, pumping (or translocating) 4 protons from the matrix through the protein into the intermembrane space.
