Question

How much amount of energy is yielded by one ml of alcohol in the body?

• A. 1 cal
• B. 4 cal
• C. 7 cal
• D. 9 cal

Hint:

Alcohol sits between protein and fat on the calorie scale, and it is called an empty calorie source.

Answer 1

The Correct Option is C

Step 1: Understanding the Question.
The question asks for the amount of energy the body gets from alcohol, a value that is often compared with the energy from carbohydrate, protein, and fat.

Step 2: Key Concept.
Each nutrient has a fixed energy value per unit when the body burns it. Carbohydrate gives 4 kcal, protein gives 4 kcal, and fat gives 9 kcal. Alcohol sits between protein or carbohydrate and fat.

Step 3: Detailed Explanation.
Alcohol yields about 7 kcal of energy per unit consumed, which is why it is often called an empty calorie source, it gives a fair amount of energy but almost no vitamins, minerals, or protein along with it. This value is higher than carbohydrate and protein, but lower than fat.
The other options do not match this standard figure. One cal is too low even for a poor energy source, 4 cal matches carbohydrate or protein, not alcohol, and 9 cal matches fat, not alcohol.

Step 4: Final Answer.
Alcohol yields about 7 cal of energy in the body, more than carbohydrate or protein, but less than fat.
