The inferior vena cava brings deoxygenated blood back into the heart from the lower body. For comparison, the part that directs deoxygenated blood from the upper body is the superior vena cava.
Answer:
The three products of cellular respiration are:
- ATP
- Water
- Carbon dioxide
Explanation:
- Cellular respiration is the process of breaking down glucose molecules to yield energy in the form of ATP.
- C6H12O6 + 6O2 → 6CO2 + 6H2O
ATP Production:
- The first step of cellular respiration, glycolysis, yields 2 net ATP.
- The second step, Kreb's cycle produces 10 NADH and 2 FADH2 molecules. Both these molecules store energy that is released in the electron transport chain to produce 34 ATP.
- Therefore, a total of 36 ATP are produced as a result of cellular respiration in eukaryotes.
Carbon dioxide Production:
- 2 molecules of CO2 are produced during the conversion of pyruvate into Acetyl Co-A by the <em>pyruvate dehydrogenase</em> complex.
- 4 molecules of CO2 are produced in the Kreb's cycle.
Water Production:
- Water is produced in the Electron Transport Chain (ETC) by the reduction of oxygen.
