Answer: (C)

The correct answer is that one gram of protein contains 4 calories. This value is essential for understanding macronutrient contributions to the diet. Proteins are made up of amino acids, which serve as the building blocks for various bodily functions, including muscle repair, enzyme production, and supporting the immune system. Knowing the caloric value of macronutrients is crucial for meal planning and dietary management. With proteins providing 4 calories per gram, it helps individuals gauge their protein intake in relation to their overall calorie needs. This is particularly important for those looking to balance their diets for weight management, muscle gain, or overall health.
