For every glucose molecule that goes through cellular respiration, how many times is a carbon molecule fully oxidized to CO₂ in the citric acid cycle?

Question

Quizplus · Accepted Answer

For every glucose molecule that enters cellular respiration, two molecules of acetyl-CoA are produced, which then enter the citric acid cycle. In each cycle, two carbon atoms are fully oxidized to CO2. Since there are two cycles per glucose (one for each acetyl-CoA), this results in a total of 4 carbon atoms being fully oxidized to CO2.
