SECTION 1: ANATOMY & PHYSIOLOGY (Questions 1–35)
Q1. Muscular, cardiopulmonary, and metabolic adaptations to exercise are known
as the:
A) Training effect
B) Homeostasis
C) Anabolic response
D) Catabolic response
Answer: A) Training effect
Rationale: The training effect refers to the physiological adaptations that
occur in response to exercise, including improvements in muscular strength,
cardiovascular efficiency, and metabolic function.
Q2. The body's automatic tendency to maintain a constant internal environment
through various processes is called:
A) Metabolism
B) Homeostasis
C) Thermoregulation
D) Adaptation
Answer: B) Homeostasis
Rationale: Homeostasis is the body's ability to maintain a stable internal
environment despite external changes. This includes regulation of temperature,
1
,pH, fluid balance, and blood glucose levels.
Q3. BMR stands for:
A) Basic Metabolic Rate
B) Basal Metabolic Rate
C) Body Mass Ratio
D) Basal Muscle Response
Answer: B) Basal Metabolic Rate
Rationale: Basal Metabolic Rate (BMR) is the number of calories the body
burns at rest to maintain basic physiological functions such as breathing,
circulation, and cell production.
Q4. Anabolism and catabolism occur at the same time throughout the body.
True or False?
Answer: True
Rationale: Anabolism (building up) and catabolism (breaking down) are
simultaneous processes in the body. While one may dominate depending on the
metabolic state (e.g., post-exercise anabolism dominates for repair), both
processes occur continuously.
Q5. A calorie is a unit of:
A) Weight
B) Heat (energy)
C) Temperature
D) Volume
Answer: B) Heat (energy)
Rationale: A calorie is a unit of heat energy. It is the amount of energy
required to raise the temperature of one gram of water by one degree Celsius.
Q6. The preferred unit in metabolic studies and nutrition labels is the:
A) Calorie (cal)
B) Kilocalorie (kcal)
2
,C) Joule
D) Watt
Answer: B) Kilocalorie (kcal)
Rationale: The kilocalorie (kcal) is the standard unit used in nutrition and
metabolic studies. One kilocalorie equals 1,000 calories. Food labels
typically use "Calories" with a capital C, which actually means kilocalories.
Q7. What are the three main categories of macronutrients?
A) Vitamins, minerals, water
B) Carbohydrates, proteins, fats
C) Carbohydrates, proteins, water
D) Fats, vitamins, minerals
Answer: B) Carbohydrates, proteins, fats
Rationale: The three macronutrients are carbohydrates, proteins, and fats.
They are required in large amounts to provide energy and support bodily
functions. Micronutrients (vitamins and minerals) are required in smaller
amounts.
Q8. Which macro-nutrient is the body's preferred source of energy?
A) Protein
B) Carbohydrate
C) Fat
D) Vitamins
Answer: B) Carbohydrate
Rationale: Carbohydrates are the body's preferred and most efficient source
of energy. They are broken down into glucose, which is used by cells for
energy production.
Q9. Approximately what percentage of the body is comprised of water?
A) 20–30%
B) 30–40%
C) 45–55%
3
, D) 55–65%
Answer: D) 55–65%
Rationale: The human body is approximately 55–65% water, depending on factors
such as age, gender, and body composition. Muscle tissue contains more water
than fat tissue.
Q10. What is the basic structural and functional unit of all living tissues?
A) The atom
B) The molecule
C) The cell
D) The tissue
Answer: C) The cell
Rationale: The cell is the basic structural and functional unit of all living
organisms. Each cell performs specific functions and contributes to the
overall function of tissues, organs, and systems.
Q11. The process of building up body tissues and storing energy is called:
A) Catabolism
B) Anabolism
C) Metabolism
D) Homeostasis
Answer: B) Anabolism
Rationale: Anabolism is the metabolic process of building up larger molecules
from smaller ones, which requires energy. It includes the synthesis of
proteins, glycogen, and fats for tissue growth and storage.
Q12. The process of breaking down body tissues to release energy is called:
A) Anabolism
B) Catabolism
C) Metabolism
D) Homeostasis
