, 6. Which macronutrient is primarily responsible for energy storage?
o A) Protein
o B) Fiber
o C) Fat
o D) Carbohydrates
Correct Option: C) Fat
Rationale: Fat serves as the primary energy storage macronutrient, providing more than
twice the energy per gram compared to carbohydrates or proteins.
7. Which mineral is critical for oxygen transport in the body?
o A) Iron
o B) Calcium
o C) Magnesium
o D) Potassium
Correct Option: A) Iron
Rationale: Iron is essential for the formation of hemoglobin, which carries oxygen in the
blood.
8. What is the primary function of carbohydrates in the body?
o A) Build and repair tissues
o B) Provide energy
o C) Regulate body temperature
o D) Absorb vitamins
Correct Option: B) Provide energy
Rationale: Carbohydrates are the body's main source of energy, particularly for the
brain and muscles during physical activity.
9. What is the term for the amount of energy expended while at rest?
o A) Active metabolic rate
o B) Total energy expenditure
o C) Basal metabolic rate (BMR)
, o D) Physiological workload
Correct Option: C) Basal metabolic rate (BMR)
Rationale: BMR represents the number of calories required to maintain basic
physiological functions at rest.
10. What type of diet is recommended for individuals with hypertension?
o A) High-sodium diet
o B) DASH diet
o C) Low-carb diet
o D) Ketogenic diet
Correct Option: B) DASH diet
Rationale: The DASH (Dietary Approaches to Stop Hypertension) diet emphasizes
fruits, vegetables, whole grains, and low sodium intake, effectively lowering blood
pressure.
11. Which vitamin is crucial for the synthesis of collagen?
o A) Vitamin A
o B) Vitamin K
o C) Vitamin D
o D) Vitamin C
Correct Option: D) Vitamin C
Rationale: Vitamin C plays a vital role in collagen synthesis, important for skin, blood
vessels, and connective tissues.
12. What is a common symptom of vitamin B12 deficiency?
o A) Hair loss
o B) Fatigue
o C) Skin rash
o D) Nausea
Correct Option: B) Fatigue
Rationale: Vitamin B12 deficiency can lead to fatigue and weakness due to its role in
red blood cell formation and energy metabolism.
