10) Respiration in the breathing sense refers to an exchange of gases. How is your breathing related to your cellular respiration? provide the overal chemical equation for cellular respiration and compare the rectants, and products, and energy yield of the three stages of cellular respiration.
Homework Answers
Cellular respiration is a process of breakdown of glucose into carbon dioxide and water to release ATP. It takes place in the presence of oxygen. Oxygen is provided when we inhale oxygen. The source of oxygen for cellular respiration is breathing.
| Stage | Reactants | Products | Energy yield |
| Glycolysis | Glucose | pyruvic acid | 2 ATP, 2 NADH |
| Pyruvate oxidation (2 rounds) | pyruvic acis | acetyl co A | 1 NADH per round |
| TCA (2 rounds) | acetyl co A | fatty acids | 1 GTP, 3 NADH, 1 FADH2 per round |
| ETC | NADH, FADH2, O2 | ATP, H2O | 28 ATP (10 NADH, 2 FADH2) |
Please rate high.
