Five gram mole of glucose on complete oxidation releases

Options

A. 3430 kcal of energy
B. 343 kcal of energy
C. 2020 kcal of energy
D. 430 kcal of energy

Answer

To find out how much energy is released by the complete oxidation of 5 gram moles of glucose, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Energy Released by 1 Mole of Glucose**:
- It is known that the complete oxidation of 1 mole of glucose releases **686 kilocalories** of energy.

2. **Determine the Number of Moles**:
- We are given **5 gram moles** of glucose. This means we need to calculate the total energy released by 5 moles.

3. **Calculate the Total Energy Released**:
- To find the total energy released by 5 moles of glucose, we multiply the energy released by 1 mole by the number of moles:
\[ \text{Total Energy} = \text{Energy per mole} \times \text{Number of moles} \]
\[ \text{Total Energy} = 686 \, \text{kcal/mole} \times 5 \, \text{moles} \]
\[ \text{Total Energy} = 3430 \, \text{kcal} \]

4. **Conclusion**:
- Therefore, the complete oxidation of 5 gram moles of glucose releases **3430 kilocalories** of energy.

### Final Answer:
The correct answer is **3430 kilocalories**.
