A business man of 70 kg weight requires 2800 kcal energy daily. How many glucose molecules and ATP molecules does he require to produce this much energy ?

Options

A. 20 molecules of glucose and 384 molecules of ATP
B. 11 molecules of glucose and 380 molecules of ATP
C. 1 Molecule of glucose and 38 molecules of ATP
D. 6 molecules of glucose and 584 molecules of ATP

Explanation

To solve the question, we need to determine how many glucose molecules and ATP molecules a businessman requires to produce 2800 kcal of energy daily.

### Step-by-Step Solution:

1. **Understand the Energy Yield from Glucose:**
- One molecule of glucose yields approximately 686 kcal of energy when completely oxidized.

2. **Calculate the Number of Glucose Molecules Required:**
- To find out how many glucose molecules are needed to produce 2800 kcal, we can use the formula:
\[ \text{Number of Glucose Molecules} = \frac{\text{Total Energy Required}}{\text{Energy from One Glucose Molecule}} \]
- Plugging in the values:
\[ \text{Number of Glucose Molecules} = \frac{2800 \text{ kcal}}{686 \text{ kcal/molecule}} \approx 4.08 \]
- Since we cannot have a fraction of a molecule, we round up to the nearest whole number. Thus, he requires **5 glucose molecules**.

3. **Calculate the ATP Molecules Produced:**
- From the complete oxidation of one glucose molecule, approximately 36 ATP molecules are produced.
- To find out how many ATP molecules are produced from 5 glucose molecules:
\[ \text{Total ATP Molecules} = \text{Number of Glucose Molecules} \times \text{ATP per Glucose} \]
- Plugging in the values:
\[ \text{Total ATP Molecules} = 5 \text{ molecules} \times 36 \text{ ATP/molecule} = 180 \text{ ATP} \]

4. **Final Answer:**
- Therefore, the businessman requires **5 glucose molecules** and produces **180 ATP molecules** to meet his energy requirement of 2800 kcal daily.

### Summary:
- **Number of Glucose Molecules Required:** 5
- **Number of ATP Molecules Produced:** 180
