Caloric value of carbohydrate per gram is

Options

A. 9.45 kcal
B. 5.65 kcal
C. 4.1 kcal
D. 9.0 kcal

Answer

To determine the caloric value of carbohydrates per gram, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Caloric Value**: Caloric value refers to the amount of energy released when a nutrient is metabolized. It is usually measured in kilocalories (kcal).

2. **Identify Macronutrients**: The three major macronutrients that provide energy are carbohydrates, proteins, and fats. Each of these macronutrients has a specific caloric value.

3. **Caloric Value of Carbohydrates**:
- Carbohydrates provide approximately 4 kilocalories per gram. This means that for every gram of carbohydrate consumed, the body can extract about 4 kilocalories of energy.

4. **Caloric Values of Other Macronutrients**:
- Proteins also provide approximately 4 kilocalories per gram.
- Fats provide a higher caloric value of approximately 9.1 kilocalories per gram.

5. **Comparing Options**: The question provides several options for the caloric value of carbohydrates:
- 9.5 kilocalorie (incorrect)
- 5.65 kilocalorie (incorrect)
- 4.1 kilocalorie (correct)
- 9.9 kilocalorie (incorrect)

6. **Conclusion**: Based on the information, the correct caloric value of carbohydrates per gram is **4.1 kilocalorie**.

### Final Answer:
The caloric value of carbohydrates per gram is **4.1 kilocalories**.
