The correct Answer is:
To solve the question regarding which nutrient has an energy value of 9.3 calories, we can follow these steps: ### Step 1: Understand the Energy Values of Nutrients We need to know the gross calorific values of the different nutrients. The main nutrients we are considering are carbohydrates, fats, proteins, and vitamins. ### Step 2: Identify the Energy Values - **Carbohydrates**: The gross calorific value is approximately **4.1 kilocalories** per gram. - **Fats**: The gross calorific value is approximately **9.4 kilocalories** per gram. - **Proteins**: The gross calorific value is approximately **5.65 kilocalories** per gram. - **Vitamins**: Vitamins do not yield energy, so they have **0 kilocalories**. ### Step 3: Compare the Values Now, we compare the values we have: - Carbohydrates: 4.1 kcal - Fats: 9.4 kcal - Proteins: 5.65 kcal - Vitamins: 0 kcal ### Step 4: Identify the Closest Value The question states that we are looking for a nutrient with an energy value of **9.3 calories**. The closest value we have is from fats, which is **9.4 kilocalories**. ### Step 5: Conclusion Since fats have the highest calorific value among the options provided and is closest to 9.3 calories, the correct answer is **fats**. ### Final Answer The nutrient that has an energy value of 9.3 calories is **fat**. ---
