Glucose → Energy
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP (energy, stored in chemical bonds)
- Krebs / Citric Acid Cycle
- Electron Transport Chain
Glycolysis (splitting sugar) yields 2 ATP and doesn’t require oxygen (so it’s good during extreme exercise).
Glycolysis + Krebs Cycle yields 36 ATP.
6H2O + 6CO2 + nutrients/sunlight → C6H12O6 + 6O2.
- Light-dependent reactions (light + H2O → NADPH + ATP)
- The Calvin Cycle (CO2 → G3P; G3P eventually becomes glucose somehow)
- Happens during the night, because daytime should be used for light-dependent reactions.
