Waec Model Questions Vol1 2021 Biology Question 26
Practice objective / multiple choice question 26 from the 2021 Waec Model Questions Vol1 Biology examination.
In a particular plant cell, aerobic respiration of one molecule of glucose yields a total of 10 NADH and 2 FADH₂ molecules across glycolysis, pyruvate oxidation and the citric acid cycle. In the electron transport chain of this cell, each NADH results in the synthesis of 2.5 ATP and each FADH₂ results in the synthesis of 1.5 ATP. Additionally, substrate‑level phosphorylation directly produces 4 ATP per glucose. What is the total number of ATP molecules generated from one glucose molecule in this cell?
