One acetyl-CoA enters the citric acid cycle and completes a single full turn. Which set of products leaves the cycle directly from that turn?

Core Concept

One turn of the citric acid cycle produces two CO2, three NADH, one FADH2, and one GTP (or ATP equivalent). The bookkeeping is correct, but the two CO2 released in the first turn generally do not correspond to the two carbon atoms in the acetyl group that just entered; those acetyl-derived carbons usually remain in cycle intermediates and can be released on later turns. Exact per-turn stoichiometry and enzyme-level carbon tracing are better treated as enrichment.
