During Cellular respiration most ATP is produced in the electron transport chain which is the last stage of cellular respiration.
Further Explanation
- Cellular respiration is the process of 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 an organelle known as mitochondrion which is known as the powerhouse of the cell.
- Cellular respiration takes place in three stages; glycolysis, Kreb's cycle and electron transport.
Glycolysis
- 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.
Kerb's cycle
- 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.
Electron transport chain
- It is the final stage of Aerobic respiration, where the six molecules of NADH and two molecules of FADH from Kreb's cycle are used to generate energy in form of ATP.
- This stage generates 34 molecules of ATP.
- Therefore, the electron transport chain is the stage of cellular respiration that yields the most energy in the form of ATP.
