Question

What is liberated by complete oxidation of glucose?

• A. Only CO\textsubscript{2}
• B. Only energy
• C. Only H\textsubscript{2}O
• D. All of these

Hint:

Energy from glucose is captured mainly as ATP during respiration.

Answer 1

The Correct Option is D

Step 1: Reaction.
Complete oxidation: C\textsubscript{6}H\textsubscript{12}O\textsubscript{6} + 6O\textsubscript{2} $\rightarrow$ 6CO\textsubscript{2} + 6H\textsubscript{2}O + Energy (ATP).
Step 2: Output.
Products are CO\textsubscript{2}, H\textsubscript{2}O and energy.
Step 3: Conclusion.
Therefore, “All of these” is correct.
