  • What is the primary function of carbohydrates?

    Carbohydrates provide energy for the body, especially for the brain and muscles.

  • What role do proteins play in nutrition?

    Proteins provide amino acids for growth, repair, and enzyme production.

  • Define micronutrients.

    Micronutrients are vitamins and minerals required in small amounts for body functions.

  • What is the difference between water-soluble and fat-soluble vitamins?

    Water-soluble vitamins dissolve in water and are not stored; fat-soluble vitamins dissolve in fat and can be stored in the body.

  • What is basal metabolic rate (BMR)?

    BMR is the energy expended to maintain basic body functions at rest.
