Page 2: Cell Biology, Enzymes, and Respiration
This page covers three major topics in GCSE AQA Biology: cell biology, enzymes, and respiration. Each section provides a comprehensive list of key concepts and questions students should be able to answer.
Cell Biology
Students should be able to:
- Label and compare plant, animal, bacterial, and yeast cells
- Explain the function of cell organelles, including ribosomes and mitochondria
- Understand specialized cells and their adaptations
- Describe tissues and organs, including examples and functions
Vocabulary: An organelle is a specialized structure within a cell that performs a specific function.
Example: The stomach is an organ composed of various tissues that work together to digest food.
Enzymes
Key concepts include:
- Understanding enzyme structure, function, and sensitivity
- Explaining the lock and key model and active sites
- Describing the effects of temperature and pH on enzyme activity
- Knowing digestive enzymes and their roles
- Understanding enzyme applications in industry and medicine
Definition: Denaturing refers to the process where an enzyme loses its shape and function due to extreme conditions.
Respiration
Students should be able to:
- Explain aerobic and anaerobic respiration, including chemical equations
- Describe where respiration occurs in cells and how energy is used
- Understand the body's response to exercise
- Explain concepts like oxygen debt and muscle fatigue
Example: The equation for aerobic respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O.
