Question

Which of the following combination of food components does not produce heat and energy in the body?
A. Carbohydrates,
B. Vitamins,
C. Water,
D. Lipids

• A. B and C only
• B. A and B only
• C. B and D only
• D. A and D only

Hint:

Remember that macronutrients like carbohydrates, lipids, and proteins are primary sources of energy, while micronutrients such as vitamins play supportive roles in metabolic processes but do not directly provide energy.

Answer 1

The Correct Option is A

Step 1: Concept
Food components that provide heat and energy to the body are known as macronutrients. These include carbohydrates, lipids, and proteins. Vitamins and minerals, on the other hand, are micronutrients and do not directly produce energy.

Step 2: Meaning
Carbohydrates, lipids, and proteins can be metabolized in the body to release energy. Water is essential for various physiological processes but does not provide heat or energy itself. Vitamins are important for metabolic reactions but are not sources of energy.

Step 3: Analysis
Carbohydrates (A) are broken down into glucose and used as a primary source of energy. Lipids (D) can be converted into fatty acids and glycerol, which are also used for energy production. Vitamins (B) assist in various metabolic processes but do not produce heat or energy directly. Water (C) is crucial for biochemical reactions but does not contribute to the body's energy supply. Therefore, both vitamins (B) and water (C) do not produce heat and energy in the body.

Step 4: Conclusion
The combination of food components that does not produce heat and energy in the body includes vitamins and water. Final Answer: (A)
