Q12. Which among the following macronutrients is composed of amino acids?
Explanation
Proteins are large, complex macronutrients composed of long chains of amino acids linked by peptide bonds. There are twenty different amino acids that combine in various sequences to form diverse proteins, each with unique functions in the body. These functions include acting as enzymes, providing structural support to tissues, and facilitating various essential metabolic processes for survival.
Q13. Consider the following statements regarding micronutrients:
I. Vitamin B12 is found mainly in animal products.
II. Folic acid deficiency during pregnancy can lead to neural tube defects.
III. Vitamin D facilitates the absorption of calcium in the gut.
IV. Vitamin K is essential for blood coagulation.
V. Vitamin C acts as an antioxidant and is fat-soluble.
Which of the above statement(s) is/are correct?
I. Vitamin B12 is found mainly in animal products.
II. Folic acid deficiency during pregnancy can lead to neural tube defects.
III. Vitamin D facilitates the absorption of calcium in the gut.
IV. Vitamin K is essential for blood coagulation.
V. Vitamin C acts as an antioxidant and is fat-soluble.
Which of the above statement(s) is/are correct?
Explanation
Vitamin B12 is primarily found in animal-based foods, and folic acid is crucial during pregnancy to prevent neural tube defects. Vitamin D is essential for intestinal calcium absorption, while Vitamin K is necessary for blood clotting. Vitamin C is an antioxidant, but it is water-soluble, not fat-soluble, which distinguishes it from vitamins like A, D, E, and K.
Q14. A deficiency of dietary iodine most commonly affects the functioning of which gland?
Explanation
The thyroid gland requires iodine to synthesize essential hormones like thyroxine and triiodothyronine, which regulate metabolism. A deficiency of dietary iodine prevents the gland from producing these hormones efficiently, leading to its enlargement, a condition known as goitre. This physical manifestation is a clear sign that the body is struggling to maintain normal endocrine function.
Q15. An individual with a sedentary lifestyle requires comparatively fewer calories. Which factor does NOT typically influence an individual’s Recommended Dietary Allowance (RDA) for energy?
Explanation
An individual’s nutritional and energy requirements are determined by factors such as age, gender, physical activity level, and physiological status, such as pregnancy or lactation. These factors influence the metabolic rate and the amount of nutrients needed for growth and maintenance. However, blood type has no scientifically established influence on the Recommended Dietary Allowance for energy or specific nutrients.
Q16. In the context of malnutrition, which of the following is considered a form of overnutrition?
Explanation
Overnutrition refers to the excessive intake of specific nutrients or total calories beyond the body’s requirements. Hypervitaminosis A is a condition resulting from the toxic accumulation of Vitamin A in the body, representing a form of micronutrient overnutrition. In contrast, conditions like pellagra result from deficiency, while cachexia and sarcopenia are characterized by the loss of body mass.
Q17. Which of the following is NOT a core component of the National Health Mission (NHM)?
Explanation
The National Health Mission focuses on strengthening the public health system and improving basic health outcomes.

This transformation focuses on shifted healthcare from being purely curative to including preventive, promotive, and rehabilitative services for the local population.
Q20. The principal function of dietary fat is to:
Explanation
Dietary fats are the most energy-dense macronutrient, providing nine kilocalories per gram. Their primary function is to serve as a concentrated energy reserve that the body can utilize during periods of low calorie intake. Additionally, fats are essential for the absorption of fat-soluble vitamins and provide insulation and protection for vital organs within the human body.Answer key for these questions
