The energy carriers that are generated during glycolysis and the citric acid cycle and then used to generate more ATP are FADH2 and NADH.
<h2>Further Explanation;</h2><h3>Cellular respiration;</h3>
- Cellular respiration is the process by which living organisms use nutrients or food substances to generate energy in the form of ATP that is required to drive cellular processes.
- Cellular respiration takes place in three stages; glycolysis, Kreb's cycle and electron transport.
<h3>Glycolysis</h3>
- It is the first stage of aerobic respiration where an organic molecule such as glucose is broken down to form 2 molecules of Acetyl-CoA and net production of 2 ATP molecules.
- Each glucose molecule yields two molecules of ATP and two molecules of Acetyl-CoA.
- During the process of glycolysis 2 molecules of energy carrier, NADH which are then taken to energy transport chain to produce more ATP.
<h3>Citric acid cycle</h3>
- It is the second phase of aerobic respiration that involves a series of reactions catalyzed by various enzymes.
- Acetyl-CoA from glycolysis undergoes a series of reaction to produce six molecules of NADH, two molecules of FADH2, together with carbon dioxide and two molecules of ATP.
- The energy carriers, NADH and FADH2 are then used to produce more ATP in the energy transport chain.
<h3>Electron transport chain</h3>
- It is the final stage of Aerobic respiration, where the six molecules of NADH and two molecules of FADH2 from Kreb's cycle and 2 NADH molecules from glycolysis are used to generate more energy in the form of ATP.
- This stage generates 34 molecules of ATP.
