, 1. Biochemistry
Key Concepts:
• Macromolecules: Structure and function of carbohydrates, lipids, proteins,
nucleic acids.
• Enzymes: Active site, substrate specificity, factors affecting enzyme
activity (temperature, pH, inhibitors).
• Metabolism: Anabolism vs. catabolism.
• Cellular Respiration: Glycolysis, Krebs cycle, electron transport chain, ATP
yield.
• Photosynthesis: Light-dependent and light-independent reactions,
chloroplast structure.
• Water and pH: Importance in biological systems, buffer systems.
Exam Questions:
1. Explain how the structure of enzymes determines their specificity and
function. Include examples.
2. Compare and contrast aerobic and anaerobic respiration in terms of
location, products, and energy yield.
3. Explain how temperature and pH can affect enzyme activity. Draw a graph
to illustrate.
4. Describe the process of the light-dependent reactions in photosynthesis
and explain their significance.
5. Discuss the role of water in biochemical reactions and in maintaining
homeostasis in cells.
