A-Level Biology - ATP - Structure | How it's Synthesised & Broken Down | Functions (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. The structure of ATP (Adenosine Triphosphate). The three components of an ATP molecule: adenine, ribose, and three phosphate groups. How ATP acts as the immediate source of energy for cell processes. 2. The ATP cycle of synthesis and breakdown. How ATP is synthesised from ADP and inorganic phosphate in a condensation reaction catalysed by ATP synthase. How ATP is broken down to release energy in a hydrolysis reaction catalysed by ATP hydrolase. 3. The functions of ATP in cellular processes. Providing energy for movement, active transport, and the synthesis of large molecules. The role of ATP in activating other molecules through phosphorylation. 4. The key properties of ATP. Features that make ATP an effective immediate energy source, such as releasing manageable amounts of energy and being rapidly re-synthesised. ** CHAPTERS ** 0:00 Introduction to ATP 0:22 The Molecular Structure of ATP 1:22 How ATP is Synthesised (ATP Synthase) 2:27 How ATP is Broken Down to Release Energy (ATP Hydrolase) 3:03 The Cellular Functions of ATP 4:12 Properties of ATP as an Immediate Energy Source ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • 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 #IB #AP
