the human diet?
A. Carbohydrates
B. Proteins
C. Vitamins
D. Fats
Rationale: Macronutrients are nutrients needed in large
amounts for energy and growth. Carbohydrates, Proteins, and
Fats provide energy; vitamins are micronutrients.
Correct Answer: A, B, D
2. What are the main functions of the cell membrane?
A. Protects the cell
B. Regulates movement of substances
C. Produces energy
D. Communicates with other cells
Rationale: The cell membrane controls what enters and exits
the cell and provides protection and signaling. Energy
production occurs in mitochondria, not the membrane.
Correct Answer: A, B, D
3. Which organelles are involved in protein synthesis?
A. Ribosomes
,B. Golgi apparatus
C. Endoplasmic reticulum (ER)
D. Lysosomes
Rationale: Ribosomes synthesize proteins, and the ER
transports them. The Golgi apparatus modifies and packages
proteins; lysosomes break down waste.
Correct Answer: A, B, C
4. Which of the following are components of the blood?
A. Plasma
B. Red blood cells
C. Platelets
D. Neurons
Rationale: Blood is composed of plasma, red and white blood
cells, and platelets. Neurons are part of the nervous system, not
blood.
Correct Answer: A, B, C
5. What are the primary functions of the skeletal system?
A. Support and structure
B. Movement
C. Blood cell production
D. Digestion of nutrients
Rationale: The skeletal system provides support, enables
movement, protects organs, and produces blood cells.
Digestion is a function of the digestive system.
Correct Answer: A, B, C
,6. Which of the following describe enzymes?
A. Biological catalysts
B. Alter reaction equilibrium
C. Increase reaction rate
D. Remain unchanged after reaction
Rationale: Enzymes speed up reactions without being
consumed; they do not change equilibrium.
Correct Answer: A, C, D
7. Which vitamins are fat-soluble?
A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin K
Rationale: Fat-soluble vitamins (A, D, E, K) are stored in fat and
liver. Vitamin C is water-soluble.
Correct Answer: A, C, D
8. Which of the following are functions of the liver?
A. Detoxification
B. Glycogen storage
C. Bile production
D. Hormone secretion
Rationale: The liver detoxifies chemicals, stores glycogen, and
produces bile; it does not secrete most hormones.
Correct Answer: A, B, C
9. Which of the following are types of muscle tissue?
A. Skeletal
, B. Cardiac
C. Smooth
D. Epithelial
Rationale: Skeletal, cardiac, and smooth are muscle types.
Epithelial is a tissue type, but not muscle.
Correct Answer: A, B, C
10. Which of the following are part of the central nervous
system (CNS)?
A. Brain
B. Spinal cord
C. Peripheral nerves
D. Meninges
Rationale: CNS consists of the brain and spinal cord. Meninges
are protective layers; peripheral nerves belong to the PNS.
Correct Answer: A, B
11. Which of the following are components of DNA?
A. Adenine
B. Thymine
C. Uracil
D. Cytosine
Rationale: DNA bases include adenine, thymine, guanine,
cytosine. Uracil is found in RNA.
Correct Answer: A, B, D
12. Which of the following hormones are produced by the
pancreas?
A. Insulin
