The glycerol-3-phosphate shuttle can transport cytosolic NADH equivalents into the mitochondrial matrix (see Fig. 15.11c). In this shuttle, the protons and electrons are donated to FAD, which is reduced to FADH,. These protons and electrons are subsequently donated to coenzyme Q in the electron transport chain. End of Chapter Problem 86a How much ATP is generated per mole of glucose when the glycerol-3-phosphate shuttle is used? ATP are generated per glucose. (Tolerance is +/- 2%) Transport of inorganic phosphate from the intermembrane space to the mitochondrial matrix affects the pH difference across the inner mitochondrial membrane. A phosphate ion enters the mitochondrial matrix in antiport with a proton (see Fig. 15.6b). This proton moves in the same direction as the protons translocated by Complexes I, II, and IV. Thus, the difference in pH between the mitochondrial matrix and the intermembrane space becomes smaller :
