The transfer steps of ATP into the cellular machinery are given below:
1. Glycolysis: (formation of Pyruvic acid)
2 ATPs + Glucose → 2 Pyruvic Acid + 4 Hydrogen + 4 ATPs
2. Formation of Acetyl CoA: (using the product of glycolysis)
2 Pyruvic Acid + 2 CoA → 2 Acetyl CoA + 2 Carbon Dioxide + 2 Hydrogen
3. Krebs Cycle:
2 Acetyl CoA + 3 O2 → 6 Hydrogen + 4 Carbon Dioxide + 2 ATPs
4. Electron Transport System:
12 Hydrogen + 3 O2 → 6 Water + 32 ATPs
Overall Reaction:
Glucose + 6 O2 → 6 Carbon Dioxide + 6 Water + 36 ATPs
The net numbers of ATP formed as the cellular machinery are 36 that are formed during the process of aerobic respiration or cellular respiration.
