During which stage in the complete oxidation of glucose are the greatest number of ATP molecules formed from ADP?

• Conversion of pyruvic acid to acetyl Co-A

• Electron transport chain

• Glycolysis

Assertion: Conversion of 1,3 biphosphoglycerate (BPGA) to 3-phospho-glyceric acid (PGA) is an energy yielding step.

Reason: This energy is trapped in the form of ATP

• If both assertion and reason are true and reason is the correct explanation of assertion.

• If both assertion and reason are true but reason is not the correct explanation of assertion.

• If assertion is true but reason is false.

• If both assertion and reason are false.

Which enzyme helps in transfer of phosphate group from ATP to a carbohydrate

• Phosphatase

• ATPase

• Phosphorylase

• Catalase

Assertion: Glucose is the favoured respiratory substrate.

Reason: When glucose is used as respiratory substrate and is completely oxidized, the RQ is 1.

• If both assertion and reason are true and reason is the correct explanation of assertion.

• If both assertion and reason are true but reason is not the correct explanation of assertion.

• If assertion is true but reason is false.

• If both assertion and reason are false.
