The first three stages of the oxidation of one molecule of glucose (glycolysis, pyruvate breakdown, and the
citric acid cycle) produce:
6 CO$_2$, 6 NADH, 6 FADH$_2$, and 6 ATP.
4 CO$_2$, 6 NADH, 3 FADH$_2$, and 6 ATP.
3 CO$_2$, 5 NADH, 1 FADH$_2$, and 2 ATP.
6 CO$_2$, 10 NADH, 2 FADH$_2$, and 4 ATP.
