Question

Which nutrient is mainly responsible for body building?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Hint:

Proteins = Growth + Repair of tissues

Answer 1

The Correct Option is B

The question asks which nutrient is mainly responsible for body building. Let's analyze each option to determine the correct answer.

1. Carbohydrates: These are the primary source of energy for the body. They are crucial for physical activity and normal brain function, but they are not primarily responsible for body building or muscle growth.
2. Proteins: Proteins are essential for body building as they are the main component of muscles, tissues, and cells. They provide the necessary amino acids required for the repair and growth of muscle tissues. This makes them the primary nutrient for body building.
3. Fats: These are a concentrated source of energy and are involved in hormone production and nutrient absorption. However, like carbohydrates, they do not primarily focus on body building.
4. Vitamins: Vitamins are essential for various biochemical and physiological processes, including immunity and bone health, but they do not directly contribute to building body muscle.

From this analysis, it is clear that Proteins are the nutrient mainly responsible for body building due to their role in muscle synthesis and repair. Therefore, the correct answer is Proteins.
