1. What is the process of converting simple sugars into complex carbohydrates called?

• A. Glycolysis
• B. Gluconeogenesis
• C. Krebs cycle
• D. Oxidative phosphorylation

Correct answer: B

Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate to produce energy. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources, such as amino acids or glycerol. C) The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. D) Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain.

2. What is the difference between isometric and isotonic muscle contractions?

• A. Isometric involves movement, while isotonic does not.
• B. Isotonic involves shortening of muscle, while isometric maintains length.
• C. Isometric uses more energy, while isotonic uses less.
• D. Isotonic involves smooth muscle, while isometric involves skeletal muscle.

Correct answer: B

Rationale: The correct answer is B: "Isotonic involves shortening of muscle, while isometric maintains length." Isometric contractions occur when the muscle generates force without changing its length, such as holding a weight in a fixed position. On the other hand, isotonic contractions involve the muscle changing length, either by shortening (concentric contraction) or lengthening (eccentric contraction) while generating force. Understanding this distinction is crucial for grasping the different types of muscle contractions and their effects on the body during exercise and movement.

3. Which of the following phrases is grammatically correct and uses parallel structure?

• A. He enjoys reading, writing, and to play sports.
• B. Walking, swimming, and cooking are his favorite hobbies.
• C. He likes to read, write, and playing sports.
• D. Singing, dancing, and to travel are his passions.

Correct answer: B

Rationale: Option B uses the gerund (-ing) form for all three hobbies, achieving parallel structure.

4. Katherine tells one of the staff, “I don’t have time to discuss the matter with you now. See me

• A. Smoothing
• B. Compromise
• C. Avoidance
• D. Restriction

Correct answer: B

Rationale: The correct answer is B: 'Compromise.' In this scenario, Katherine is willing to engage with the staff member but suggests they postpone the discussion to a later time. This demonstrates a willingness to find a middle ground or reach a mutual agreement, which aligns with the concept of compromise. 'Smoothing' involves downplaying differences to maintain harmony, 'Avoidance' is ignoring or postponing the issue altogether, and 'Restriction' refers to limiting the interaction or communication. Therefore, 'Compromise' best fits the situation where Katherine is open to discussing the matter at a more suitable time.

5. Which part of the brain is responsible for coordinating muscle movements, maintaining balance, and posture?

• A. Cerebrum
• B. Cerebellum
• C. Medulla oblongata
• D. Thalamus

Correct answer: b

Rationale: The correct answer is B: Cerebellum. The cerebellum is responsible for coordinating muscle movements, maintaining balance, and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate voluntary movements. The cerebrum, on the other hand, is mainly responsible for higher brain functions such as thinking and problem-solving. The medulla oblongata controls autonomic functions like breathing and heart rate, while the thalamus acts as a relay station for sensory information. Therefore, the cerebellum is the specific part of the brain that plays a crucial role in motor coordination and balance.

6. 12 is a/an:

• A. even number
• B. odd number
• C. prime number
• D. composite number

Correct answer: A

Rationale: Even numbers are integers divisible by 2 without a remainder. Since 12 divided by 2 equals 6 with no remainder, 12 is even.
