1. What enzyme plays a key role in breaking down carbohydrates in the small intestine?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: C

Rationale: Amylase, produced by the pancreas and salivary glands, breaks down carbohydrates into simple sugars like glucose.

2. What is the breakdown product of creatine phosphate, an energy source used for short bursts of muscle activity?

• A. Glucose
• B. Lactic acid
• C. Carbon dioxide
• D. Creatine

Correct answer: D

Rationale: The breakdown product of creatine phosphate is creatine. Creatine phosphate is stored in muscle cells and rapidly converts to creatine to provide energy for short bursts of muscle activity, such as weightlifting or sprinting. It is not converted into glucose, lactic acid, or carbon dioxide. Creatine is then further broken down into creatinine, which is excreted in urine. Therefore, the correct answer is D: Creatine.

3. The passage implies that achieving energy sustainability requires...

• A. solely relying on renewable energy sources for electricity generation.
• B. a combination of advancements in renewable energy production and management technologies.

5. Stephanie is often seen interacting with the medical intern during coffee breaks and after duty

• A. Formal
• B. Informal
• C. Staff
• D. Line

Correct answer: B

Rationale: The correct answer is 'B: Informal.' Stephanie's interactions with the medical intern during coffee breaks and after duty suggest a casual and friendly relationship, rather than a formal or official one. 'Informal' describes interactions that are relaxed, personal, and not bound by strict professional protocols. In contrast, 'formal' interactions would involve more structured and official communication, such as meetings or professional discussions. 'Staff' and 'line' are not relevant in this context, as they do not describe the nature of the relationship between Stephanie and the medical intern.

6. Cartilage, found in joints and the ear, is a type of:

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: B

Rationale: The correct answer is B: Connective tissue. Cartilage is a tough, flexible type of connective tissue that provides support and cushioning in joints and the ear. It is made up of specialized cells called chondrocytes embedded in a gel-like matrix of collagen and proteoglycans. Epithelial tissue (A) covers and lines body surfaces, muscle tissue (C) is responsible for movement, and nervous tissue (D) transmits signals in the body. In contrast, cartilage primarily serves a structural and protective function, placing it within the category of connective tissue.
