Answer 1

Correct Answer: One gram fat

Rationale:

Among the macronutrients, fats provide the most energy per gram. Specifically, one gram of fat provides approximately 9 calories of energy, which is more than double the amount provided by carbohydrates and proteins.
Carbohydrates and proteins each provide about 4 calories per gram. Therefore, fat is the most energy-dense macronutrient, making it a significant source of energy for the body.

Explanation of Other Options:

One gram carbohydrate

Rationale: Carbohydrates are a primary source of energy and provide about 4 calories per gram. They are quickly metabolized by the body to provide immediate energy, which is why they are important for quick bursts of activity.

One gram protein

Rationale: Proteins also provide approximately 4 calories per gram. They are essential for the growth, repair, and maintenance of tissues in the body. However, they are not typically used as a primary energy source unless carbohydrate stores are low.

One gram vitamin A

Rationale: Vitamins, including vitamin A, do not provide calories or energy. Instead, they play crucial roles in various biochemical processes in the body. Vitamin A is important for vision, immune function, and cell growth.

Conclusion:

Among the given options, one gram of fat provides the highest amount of energy, making it the most energy-dense nutrient. This is important for understanding dietary choices and energy management in the body.
