WebCitric Acid Cycle The TCA cycle is a set of eight catalyzed reactions and eight intermediates that break down hydrocarbon substrates into carbon dioxide (CO2) and water (H2O) using the energy released to protonate nicotinamide adenine dinucleotide converting from NAD+ to NADH or flavin adenine dinucleotide from FADH to FADH2. WebA. The amount of acetyl CoA produced from carbohydrate metabolism that enters the citric acid cycle would be decreased. B. A decrease in the amount of NADH would likely decrease activity of citrate synthase. C. Flux through the citric acid cycle would cease until adequate pyruvate is available.
