How many ATP molecules are produced by the citric acid cycle?

The correct answer is: 24 ATP

• Cellular respiration happens in living organisms when food components are broken down and the energy released is stored in the form of ATP, which is needed to execute a range of vital processes.
• Carbohydrate is the principal respiratory substrate.
• Glycolysis is the initial stage of cellular respiration and occurs in the cytoplasm of all living things. It can also be found in anaerobic organisms because it does not require oxygen. It is a multi-step enzymatic reaction that results in the partial oxidation of glucose and the formation of two molecules of pyruvate.
• There is a net gain of 24 ATPs during glycolysis.
