Study Notes
Glycolysis
- Reactants: 2 ATP, 1 Glucose, G3P contribute to the breakdown of glucose.
- Products: 2 NADH, 2 ATP, and 2 Pyruvate are generated, storing energy and molecules for further processes.
- Occurs in the cytosol, the fluid portion of the cytoplasm.
Pyruvate Oxidation
- Reactant: 2 Pyruvate molecules are converted during this stage.
- Products: 2 NADH, 2 CO2, and 2 Acetyl CoA are produced, linking glycolysis to the Krebs cycle.
- Location: Takes place in the mitochondrion.
Krebs Cycle (Citric Acid Cycle)
- Reactants: 2 Acetyl CoA and oxaloacetate enter the cycle to initiate a series of reactions.
- Products: 6 NADH, 4 CO2, 2 FADH2, and 2 ATP are generated, facilitating energy extraction and carbon release.
- Occurs in the matrix of the mitochondrion, the innermost compartment.
Oxidative Phosphorylation
- Reactants: 6 O2 and energy carriers (2 FADH2, 10 NADH) are utilized to drive ATP production.
- Products: 6 H2O and 34 ATP are produced, capturing significant energy for the cell.
- Takes place in the cristae, the folds of the inner mitochondrial membrane.
Fermentation
-
Alcohol Fermentation:
- Reactants: 2 NADH and 2 Pyruvates are transformed in anaerobic conditions.
- Products: 2 CO2 and 2 Ethanol are produced, allowing for ATP production without oxygen.
- Occurs in the cytosol.
-
Lactic Acid Fermentation:
- Reactants: 2 NADH and 2 Pyruvates are utilized in this anaerobic process.
- Products: 2 Lactic Acid are generated, allowing for temporary energy production.
- Also occurs in the cytosol.
