Question

When one glucose molecule is completely oxidised, it changes

• A. 36 ADP molecules into 36 ATP molecules
• B. 38 ADP molecules into 38 ATP molecules
• C. 30 ADP molecules into 30 ATP molecules
• D. 32 ADP molecules into 32 ATP molecules.

Answer 1

Answer: (B)

Aerobic respiration is the process of complete oxidation of organic foods into carbon dioxide and water in presence of oxygen. It has three steps: Glycolysis - occurs in the cytoplasm, common in both aerobic and anaerobic respiration. One glucose molecule is broken into two molecules of pyruvates. The net ATP produced is 8. Krebs cycle - it is the citric acid cycle and the process of oxidation and degradation of acetate which is obtained from pyruvate. The net ATP produced is 24 ATP. Terminal oxidation - It has different carriers of electrons which creates an electron gradient in the membranous matrix. So, the correct option is ' 38 ADP molecules and 38 ATP molecules'.
