When one glucose molecule is completely oxidised, it changes

1. 36 ADP molecules into 36 ATP molecules
2. 38 ADP molecules into 38 ATP molecules
3. 30 ADP molecules into 30 ATP molecules
4. 32 ADP molecules into 32 ATP molecules

Correct answer: 38 ADP molecules into 38 ATP molecules

Solution

In standard biology texts, complete oxidation of one glucose molecule under aerobic conditions yields 38 ATP. That means 38 ADP molecules are phosphorylated to 38 ATP molecules.
