Cellular Respiration Formula:
The first step in both cellular respiration and fermentation. This means, gylcolysis is both aerobic and anaerobic. Gylcolysis occurs in the cytoplasm of all living organism cells (prokaryotic and eukaryotic).
- Glycolysis changes C6H12O6 into 2 C3H4O3 (glucose into Pyruvic Acid)
- A net of 2 ATP are made
- 2 NADH are made
The second step in cellular respiration. The Krebs Cycle takes place in the Matrix (the liquid substance) of the mitochondria. The pyruvic acid is broken down into carbon dioxide. More NADH and NADH2 are made. The Krebs Cycle also releases two more ATP.
Electron Transport Chain:
Is also known as oxidative phosphorylation, which occurs in the Cristae (the folds of the Inner Membrane) of the mitochondria. NADH and FADH2 are used. The high energy electrons that come from the Krebs Cycle are used to convert ATP into ATP. Which means, oxygen is a reactant and water is a product.
