Substrates as electron donors

Description

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

Abbreviation: S_red
