A-Level Biology - Glycolysis - What It Is | Key Stages | Reactants & Products (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. An overview of glycolysis The difference between aerobic and anaerobic respiration Where glycolysis occurs within the cell The stages of aerobic respiration 2. Oxidation and reduction in respiration The meaning of oxidation and reduction The role of electron carriers such as NAD 3. The main steps of glycolysis The phosphorylation of glucose to form hexose bisphosphate The lysis of hexose bisphosphate into triose phosphate The phosphorylation of triose phosphate Dehydrogenation to produce pyruvate, ATP and reduced NAD 4. A summary of the reactants and products The net gain of ATP, pyruvate and reduced NAD from one glucose molecule ** EXAM BOARD SPECIFIC INFO ** AQA - You don't need to know the names of the intermediate molecules in glycolysis apart from triose phosphate OCR - Everything is relevant to your course! CIE - In your exam board, hexose bisphosphate is called fructose 1,6 bisphosphate, and you don't need to know the name of the intermediate molecule triose bisphosphate ** CHAPTERS ** 0:18 What is glycolysis? 1:54 Oxidation and reduction 2:53 The main steps of glycolysis 5:26 Reactants and products of glycolysis ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • KS3 Physics      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #Alevel #Biology #study #revision #school #exam #AQA #OCR #Edexcel
