Substrates as electron donors
Description
Mitochondrial respiration depends on a continuous flow of electron-supplying substrates across the mitochondrial membranes into the matrix space. Substrates as electron donors are reduced fuel compounds Sred that are oxidized to an oxidized product Pox during H+-linked electron transfer, Sred → Pox + 2{H+ + e-}. Many substrates are strong anions that cannot permeate lipid membranes and hence require carriers.
