WebThe citric acid cycle is regulated mainly by the availability of key substrates, particularly the ratio of NAD + to NADH and the concentrations of calcium, inorganic phosphate, ATP, ADP, and AMP. Citrate – the ion that gives its name to the cycle – is a feedback inhibitor of citrate synthase and also inhibits PFK, providing a direct link between the regulation of … Web29 okt. 2024 · The citric acid cycle is regulated primarily by the concentration of ATP and NADH. The key control points are the enzymes isocitrate dehydrogenase and α-ketoglutarate dehydrogenase. It is important to note that several steps in the cycle require NAD + or FAD, which are abundant only when the energy charge is low.The citric acid …
