Level 1: Core Concepts Check (Aiming for a Pass - 'S')

1. Define: What is a bio-molecule?

2. List: Name the four major groups of bio-molecules.

3. Identify: What are the basic building blocks (monomers) of proteins?

4. List: Name the chemical elements found in all carbohydrates.

5. Describe: What is the specific food test used to identify starch, and what is the positive result?

6. Define: What is an enzyme?

7. Identify: Name the most common inorganic compound in all living things.

8. List: Name two minerals essential for the human body and state one function for each.

9. Identify: What disease is caused by a deficiency of Vitamin C?

Level 2: Connecting the Dots (Aiming for a Credit - 'C')

1. Compare: Explain two main differences between carbohydrates and lipids in terms of their function and elemental composition.

2. Explain: Describe the process for testing a food sample for glucose (a reducing sugar). Include the reagent, the necessary condition (e.g., heating), and the range of colour changes.

3. Describe: Using examples, explain the difference between a monosaccharide, a disaccharide, and a polysaccharide.

4. Explain the role: Why are enzymes considered biological catalysts? Explain their importance in living organisms.

5. Discuss: Water has several unique properties that are essential for life. Describe two of these properties and explain why they are important.

Level 3: Exam Challenge (Aiming for a Distinction - 'A'/'B')

1. Scenario Analysis: A school canteen provides lunch packets containing rice, dhal curry, and coconut sambol. (a) Name the main bio-molecule found in each food item. (b) A student wants to confirm the presence of protein in the dhal curry. Describe, step-by-step, the experiment they should conduct, including the reagents and the expected observation for a positive result. (c) Explain the importance of including all three food types for a balanced diet, referring to the functions of the bio-molecules you identified.
