The main role of the TCA (Tricarboxylic Acid) cycle, also known as the citric acid cycle or Krebs cycle, is to generate a lot of H+ (hydrogen ions) and produce most of the ATP (adenosine triphosphate) that is synthesized in cellular respiration. It does not involve the production of pyruvic acid, as pyruvic acid is formed during glycolysis. Gluconeogenesis is a separate process involved in the synthesis of glucose from non-carbohydrate sources.
The main role of the TCA (Tricarboxylic Acid) cycle, also known as the citric acid cycle or Krebs cycle, is the creation of most of the ATP that is synthesized in the cell. During this cycle, the carbon molecules derived from carbohydrates, fats, and proteins are oxidized to produce energy in the form of ATP. Additionally, the TCA cycle also generates a significant amount of reducing power in the form of NADH and FADH2, which are used by the electron transport chain to produce more ATP. The TCA cycle is not directly involved in the synthesis of pyruvic acid, glycolysis, generation of a lot of H+, or gluconeogenesis.
