Biology — Biochemistry and Respiration

Exam board: AQA  |  Back to subjects

Board-Specific Note

AQA specification; content aligns with the national A-Level syllabus.

Learning Objectives

• Describe the biochemistry of respiration
• Understand enzymes
• Explain the electron transport chain

Key Points

• Glycolysis, Krebs cycle
• ATP as energy currency
• Enzymes lower activation energy

Lesson Plan (50 minutes)

1. Starter (5 min): Recall prior knowledge of biochemistry and respiration with quick questions.
2. Teaching (15 min): Work through each of the learning objectives, explaining principles step by step.
3. Key points review (5 min): Revisit the key points together, confirming understanding.
4. Worked example (10 min): Model the example question: Where does glycolysis occur?. Solution: In the cytoplasm
5. Practice (10 min): Students attempt the practice questions independently; circulate and support.
6. Plenary (5 min): Review answers and address misconceptions.

Homework

• Name the products of glycolysis
• What is the role of ATP?
• Define active site

Assessment

Check practice answers against the model answer; use the built-in practice questions as formative assessment.
