1. Cellular respiration C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP) Or
Glucose + Oxygen → Carbon dioxide + Water + Energy (as ATP)

2. Cellular respiration glycolysis kreb cycle ETc

3. Cellular respiration kreb cycle/Citric acid cycle

4. Cellular respiration kreb cycle/Citric acid cycle

5. Cellular respiration kreb cycle/Citric acid cycle

6. Glucose In glycolysis: In Kreb Cycle: 2 ATP (net) 1 ATP x 2 = 2 ATP
Kreb Cycle yields a total of 6 CO2 molecules.

7. Cellular respiration glycolysis Kreb cycle ETC ATP Produced
2 ATP 2 ATP ATP
2 NADH 8 NADH 10 NADH 30 ATP
2 FADH2 2 FADH2 4 ATP
NADH and FADH get oxidized in the Electron transport chain.
Every NADH Produces 3 ATP
Every FADH2 produces 2 ATP
TOTAL: 38 ATP
