How is citric acid cycle regulated
http://pressbooks-dev.oer.hawaii.edu/biology/chapter/regulation-of-cellular-respiration/ 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 …

These enzymes are isocitrate dehydrogenase … WebClicker Question 23, Response Which product from oxidation of fatty acids CANNOT feed into the citric acid cycle? D. NADP + The acetyl-CoA resulting from all the β-oxidation pathways, the succinyl Co-A formed by the oxidation of odd-number fatty acids, and the succinate resulting from the oxidation of polyunsaturated fatty acids can all feed into the …
WebSteps in the Citric Acid Cycle. Step 1. The first step is a condensation step, combining the two-carbon acetyl group (from acetyl CoA) with a four-carbon oxaloacetate molecule to form a six-carbon molecule of citrate. CoA is bound to a sulfhydryl group (-SH) and diffuses away to eventually combine with another acetyl group.
