Table 1: How Do You Make ATP from Glucose?
| Location | Starts with | Ends with | Stored Forms of Energy (ATP, NADH, or FADH2) | |
|---|---|---|---|---|
| Glycolysis | Cytoplasm | glucose (C 6H 12O6) + 2 ATP + 2 NAD+ | 2 pyruvate (C 3H 4O3) + 2 (net) ATP + 2 NADH | ATP |
| Pyruvate oxidation | mitochondrial matrix | 2 pyruvate + 2 NAD+ + 2 Coenzyme A complexes | 2 acetyl coenzyme A (acetyl CoA) + 2 CO2 + 2 NADH | NADH |
| Citric Acid Cycle | mitochondrial matrix | 2 acetyl CoA + 6 NAD+ + 2 FAD (+ oxaloacetate ) | oxaloacetate + 4 CO2 + 2 ATP + 6NADH + 2 FADH2 | FADH2 |
| Oxidative Phosphorylation |
Lecture Notes
In cellular respiration the energy is transferred to the bonds between the phosphate groups ATP.
ATP can be used by cells as a source of energy by breaking the high-energy phosphate bonds.
The energy in glucose is stored in the chemical bonds between the atoms. It is not directly available for your cells to use.
