How many calories are in 1 gram of protein?

2 calories
4 calories
7 calories
9 calories

The correct answer is: 2 calories

Protein is one of the three macronutrients that provide energy to the body. Of the three, protein is the only one that contains nitrogen, which contributes to its higher energy content. However, despite this difference, protein still provides only 4 calories per gram, just like carbohydrates. The options B, C, and D are incorrect because they provide either the incorrect calorie amount or confuse protein with a different macronutrient. Option B, 4 calories, is the correct amount of energy provided by one gram of protein. Option C, 7 calories, is closer to the energy content of one gram of alcohol, which is 7 calories. Option D, 9 calories, is the energy content of one gram of fat, the macronutrient with the highest calorie amount. Therefore, option A, 2 calories, is the incorrect answer.
