Study Notes
Glycolysis
- Reactants include glucose, 2 ATP, NAD+, ADP, and a phosphate group (P).
- End products are 2 pyruvate molecules, 2 ATP, and 2 NADH.
Krebs Cycle
- Reactants consist of 2 Acetyl CoA, 6 NAD+, FAD, 6 ADP, and a phosphate group (P).
- Resulting end products are 4 carbon dioxide (CO2), 6 NADH, 2 FADH2, 2 ATP, and water (H2O).
- The cycle releases high-energy electrons captured by NADH and FADH2.
Oxidative Phosphorylation
- Requires NADH, FADH2, oxygen (O2), ADP, and a phosphate group (P) as reactants.
- Produces 32-34 ATP, water (H2O), and regenerates NAD+ and FAD.
Overall Cellular Respiration
- The equation represents the overall reaction as glucose (C6H12O6), water, and oxygen yield carbon dioxide, water, and energy (ATP).
- The process efficiently converts biochemical energy from nutrients into usable ATP through several metabolic stages.
