A single ATP produce

Options

A. 8 kcal
B. 10 kcal
C. 12 kcal
D. 100 kcal

Explanation

To solve the question regarding the energy produced by a single ATP molecule, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understand ATP**: ATP stands for adenosine triphosphate. It is the primary energy carrier in cells, providing energy for various cellular processes.

2. **Hydrolysis of ATP**: When ATP is hydrolyzed (broken down), it converts into adenosine diphosphate (ADP) and an inorganic phosphate (Pi). This reaction releases energy.

3. **Energy Released**: The energy released during the hydrolysis of one mole of ATP is approximately 30.5 kJ (kilojoules). When converted to kilocalories, this is about 7.5 kcal.

4. **Select the Closest Answer**: The question provides options of 8 kcal, 10 kcal, 12 kcal, and 100 kcal. Since the energy released from the hydrolysis of one mole of ATP is approximately 7.5 kcal, the closest answer is 8 kcal.

5. **Conclusion**: Therefore, the answer to the question "A single ATP produced" is approximately 8 kilocalories.

### Final Answer:
The energy produced by a single ATP molecule during hydrolysis is approximately **8 kilocalories**.
