Edexcel A Level Biology B Topic 5: Energy for Biological Processes – Subtopic 5.2 Oxidative Phosphorylation & Anaerobic Respiration Complete Pack

Exam-board-aligned Edexcel A Level Biology B Oxidative Phosphorylation & Anaerobic Respiration pack with exam questions, retrieval practice, misconceptions and teacher mark scheme.

This resource is a complete exam-style assessment pack for Edexcel A Level Biology B, covering Topic 5: Energy for Biological Processes, Subtopic 5.2 – Oxidative Phosphorylation & Anaerobic Respiration (5.4–5.5).

NOTE: Word documents for student questions and the mark scheme are included for ease of editing, copying and adapting.

It has been written to closely reflect Edexcel command words, mark scheme phrasing and examiner expectations, making it ideal for both classroom teaching and focused exam preparation.

What’s included
Student Pack

• Structured exam-style questions using Edexcel command words
• Short answer, structured, data-handling and extended response questions
• Challenging application and data analysis tasks (including inhibitor and respiration data questions)
• Retrieval practice questions to consolidate understanding of oxidative phosphorylation and anaerobic pathways

Teacher Pack
