The tricarboxylic acid cycle, commonly known as the Krebs cycle, is a sequence of events that release stored energy by oxidizing acetyl CoA, which is produced from carbs, proteins, and fats.

The continuous flow or occurrence of the citric acid cycle without any obstruction is referred to as the rate of flux. The following are the most important factors in maintaining the citric acid cycle's flux:

• Isocitrate dehydrogenase, is an enzyme that catalyzes the conversion of isocitrate to a-ketoglutarate and is allosterically activated by adenosine diphosphate (ADP).
• $\mathrm{Î\pm }$-ketoglutarate dehydrogenase is an enzyme that catalyzes the conversion of $\mathrm{Î\pm }$-ketoglutarate to succinyl CoA.
• Adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide concentrations (NADH).
• The availability of the substrate.
