• A. Erepsim
• B. Pepsin
• C. Mucin
• D. Amylase

Explanation: The small intestine produces intestinal juice containing erepsin, a group of peptidases that completes protein digestion.

• A. Vitamins
• B. Proteins
• C. Tissues
• D. Hemoglobin

Explanation: Proteins are commonly called the body’s building blocks because they form and repair muscles, tissues, enzymes, and other structures.

• A. Upper most layer
• B. none of these
• C. Connective Tissues
• D. Adipose tissues

Explanation: Adipose tissue is the body’s main storage site for fat, including triglycerides that can be broken down to release fatty acids.

• A. Rickets
• B. Scurvy
• C. Beri Beri
• D. Night blindness

Explanation: Vitamin D helps the intestine absorb calcium and supports normal bone mineralisation; its deficiency causes rickets in children.

• A. Scurvey
• B. Rickets
• C. Beri Beri

• A. Vitamin B
• B. Vitamin B complex
• C. Vitamin D

Explanation: Ascorbic acid is the chemical name for vitamin C and is important for collagen formation, wound healing and immune function.

• A. strength dominating sports
• B. Endurance dominating sports
• C. both a & B
• D. none of these

Explanation: Strength-dominating sports place greater demand on muscle repair and growth, so protein forms a comparatively major part of the diet.

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

Explanation: Endurance exercise requires prolonged energy, and carbohydrates are the body’s most readily available fuel for this purpose.

• A. Mineral salts
• B. Fats
• C. Calcium
• D. none of these

Explanation: Calcium is the important mineral in milk and supports the formation and maintenance of bones and teeth.

• A. They have more affinity to oxygen
• B. more dynamic
• C. more powerful
• D. they have carry Co2 capacity

Explanation: Carbohydrates can be oxidised to produce energy with less oxygen than fats, making them especially useful during vigorous exercise.

• A. Amylase
• B. Lipase
• C. Trypsin
• D. none of these

Explanation: Trypsin is a proteolytic enzyme that breaks proteins into smaller peptides in the small intestine.

• A. A
• B. K
• C. D
• D. C

Explanation: Vitamin C is water-soluble and is readily destroyed by heat, oxygen and prolonged storage.
