Page 1: Introduction to GCSE AQA Biology Revision

This page introduces the GCSE AQA Biology Paper 1 and Paper 2 revision notes, providing a framework for students to assess their knowledge. It encourages students to review the following questions and mark their understanding using a simple system:

• Tick for answers they are 100% sure about
• Cross for answers they need help with
• Question mark for answers they are unsure about

This self-assessment approach helps students identify areas where they need to focus their revision efforts, ensuring a more effective study strategy for both Biology Paper 1 topics AQA and Biology Paper 2 topics AQA.

Highlight: This self-assessment technique is crucial for efficient revision, allowing students to prioritize their study time on areas that need the most attention.

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.
