1What is the primary physiological function of proteins in the human body?
A.Providing the body's primary energy store for long-term endurance
B.Growth, repair of damaged body tissues, and synthesis of enzymes and hormones
C.Insulating internal organs against mechanical shock and thermal loss
D.Facilitating the absorption of fat-soluble vitamins in the small intestine
Explanation: Proteins are fundamental structural macronutrients essential for growth, tissue repair, and the production of vital body chemicals including enzymes, antibodies, and hormones.
2What distinguishes High Biological Value (HBV) proteins from Low Biological Value (LBV) proteins?
A.HBV proteins contain all essential amino acids in sufficient proportions required by the human body
B.HBV proteins contain higher amounts of saturated fats and dietary cholesterol
C.HBV proteins are easier to digest because they dissolve completely in cold water
D.HBV proteins are derived exclusively from plant sources such as legumes and cereals
Explanation: HBV proteins provide all nine essential amino acids in proportions suitable for human tissue synthesis. Most animal-derived foods (meat, fish, eggs, dairy) and soya beans contain HBV protein.
3Which food item is classified as a source of High Biological Value (HBV) protein?
A.Wholemeal bread
B.Chicken breast
C.Red kidney beans
D.White long-grain rice
Explanation: Chicken breast is an animal food source containing all essential amino acids, making it a complete or High Biological Value (HBV) protein.
4What is the primary function of carbohydrates in the human diet?
A.Forming structural cell membranes and myelin sheaths
B.Providing the body with its main and most readily available source of energy
C.Transporting iron ions in the bloodstream
D.Synthesising steroid hormones and bile salts
Explanation: Carbohydrates are broken down into glucose during digestion, serving as the body's primary fuel source for physical activity and metabolic functions.
5Which sugar is classified as a monosaccharide?
A.Sucrose
B.Glucose
C.Lactose
D.Maltose
Explanation: Glucose is a single-unit simple sugar (monosaccharide), alongside fructose and galactose.
6What is the primary role of dietary fibre (non-starch polysaccharides) in the digestive system?
A.Providing 9 kcal of energy per gram during cellular respiration
B.Adding bulk to faeces and stimulating peristalsis to prevent constipation
C.Neutralising stomach acid in the duodenum
D.Emulsifying dietary lipids into microscopic droplets
Explanation: Dietary fibre passes through the digestive tract largely undigested, absorbing water to add bulk to stool and stimulating rhythmic muscular contractions (peristalsis) of the intestinal walls.
7How do saturated fatty acids differ chemically from unsaturated fatty acids?
A.Saturated fatty acids contain double bonds between carbon atoms, whereas unsaturated fatty acids contain only single bonds
B.Saturated fatty acids contain no double bonds between carbon atoms and are fully saturated with hydrogen atoms
C.Saturated fatty acids are always liquid at room temperature
D.Saturated fatty acids contain amino groups attached to the hydrocarbon chain
Explanation: Saturated fatty acids have only single carbon-to-carbon bonds (C-C), holding the maximum possible number of hydrogen atoms. Unsaturated fatty acids contain one or more double bonds (C=C).
8Which set of vitamins belongs to the fat-soluble group?
A.Vitamins B1, B2, B6, and B12
B.Vitamins A, D, E, and K
C.Vitamins C, B9, and B3
D.Vitamins B complex and C
Explanation: Vitamins A, D, E, and K are fat-soluble vitamins stored in the liver and adipose tissue. B-complex vitamins and Vitamin C are water-soluble.
9Which deficiency disease is caused by a severe lack of Vitamin C (ascorbic acid) in the diet?
A.Beriberi
B.Scurvy
C.Pellagra
D.Rickets
Explanation: Vitamin C deficiency leads to scurvy, characterized by bleeding gums, poor wound healing, joint pain, and subcutaneous hemorrhages due to impaired collagen synthesis.
10Which mineral is required in large quantities for the formation and maintenance of strong bones and teeth?
A.Iron
B.Calcium
C.Iodine
D.Sodium
Explanation: Calcium combines with phosphorus to form calcium phosphate, giving rigidity and strength to bones and teeth.
