3.1.6 L1 ATP: Structure, Function, and Synthesis (AQA A-level)

This lesson introduces students to the structure, function, and biological importance of ATP (adenosine triphosphate), aligning with the AQA A-level Biology specification on Biological Molecules. The lesson covers the following key areas:

What ATP is: Students will learn what ATP is and why it’s considered the cell’s immediate energy source.
Structure of ATP: Students will explore the structure of ATP, including its components (adenine, ribose, and three phosphate groups).
ATP Hydrolysis and Synthesis: The lesson explains how ATP is hydrolyzed to release energy (ATP → ADP + Pi) and how it is synthesized through processes such as oxidative phosphorylation, photophosphorylation, and substrate-level phosphorylation.
Role of ATP in Cellular Processes: Students will understand how ATP is used in metabolic reactions, active transport, muscle contraction, and the synthesis of macromolecules.
