An organism uses only the glycerophosphate shunt pathway to transport cytosolic NADH to mitochondria. For every two electrons transported, complex I, complex III, and complex IV of the electron transport chain in this organism transport 2.5, 1.5, and 2.0 protons (H⁺), respectively. The H⁺ to ATP ratio of F₀F₁-ATPase of this organism is 4.0. Terminal electron acceptor is oxygen.
The number of ATP molecules synthesized by oxidizing NADH from glycolysis is ________ (rounded off to two decimal places).
