The reason malonic acid act as a competitive inhibitor and not a substrate for succinate dehydrogenase should be determined. Effect on the concentration of intermediates of the cycle, after the addition of malonic acid to citric acid cycle, should be determined. Concept introduction: The citric acid cycle is a catabolic process. It is a series of chemical reactions in which the stored energy of the body is released by the oxidation of acetyl-Coenzyme A. Pyruvate dehydrogenase enzyme complex is required for the linking of glycolysis and TCA. It helps in the conversion of pyruvate into Acetyl CoA. Acetyl CoA then enters into the series of the citric acid cycle.

How does a voltage-gated sodium channel work? Specifically, how and why does a change in voltage trigger their opening? Please be detailed

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
