Neco Model Questions Vol1 2022 Biology Question 10
Practice objective / multiple choice question 10 from the 2022 Neco Model Questions Vol1 Biology examination.
A cell metabolises two molecules of glucose under aerobic conditions. For each glucose the following yields are obtained: glycolysis produces 2 ATP (substrate‑level) and 2 cytosolic NADH; each cytosolic NADH yields 3 ATP via the malate‑aspartate shuttle. Pyruvate oxidation generates 2 mitochondrial NADH, but transporting each pyruvate into the mitochondrion costs 2 ATP. The citric‑acid cycle yields per glucose 6 mitochondrial NADH, 2 FADH\(_2\) and 2 GTP (equivalent to ATP). Each mitochondrial NADH yields 3 ATP and each FADH\(_2\) yields 2 ATP. Determine the total net ATP produced from the two glucose molecules.
