In aerobic respiration which of the following is correct?
Correct answer: A. Pyruvate is completely oxidized to form carbon dioxide and water
- A. Pyruvate is completely oxidized to form carbon dioxide and water
- B. Pyruvate is completely oxidized to form oxygen and water
- C. Pyruvate carboxylated to produce citrate
- D. Pyruvate is converted to ethanol and carbon dioxide
Explanation
In aerobic respiration, glucose is oxidised to form pyruvate during glycolysis. This is followed by Link reaction, Krebs cycle and Electron transport chain all of which leads to the formation of ATP, water and CO2. During the citric acid cycle, pyruvate is completely oxidized, converting it into carbon dioxide (CO2) and high-energy electron carriers (NADH and FADH2).
