Neco 2023 Biology Question 2

The diagram shows the structure of a mitochondrion. During aerobic respiration, NADH and FADH\(_2\) generated in earlier stages donate electrons to the electron transport chain located in the inner mitochondrial membrane. Given that glycolysis produces \(2\) NADH, the link reaction produces \(2\) NADH, and the Krebs cycle produces \(6\) NADH and \(2\) FADH\(_2\) per molecule of glucose, and assuming P/O ratios of \(2.5\) ATP per NADH and \(1.5\) ATP per FADH\(_2\), calculate the total number of ATP molecules synthesized from oxidative phosphorylation per glucose molecule. Also include the substrate‑level ATP formed in glycolysis (\(2\) ATP) and the Krebs cycle (\(2\) ATP).
