ATP  ATP Adenosine triphosphate (ATP) is the energy currency of cells ATP ATP - ADP CYCLE Prepared by: Ann Lorien T. Etchineque, LPT ATP-ADP CYCLE  Energy Transition During Exercise Beyond 3 minutes: Low Intensity The body relies more on aerobic respiration Up to 2-3 minutes: High Intensity Anaerobic glycolysis kicks in to keep energy flowing. First few seconds: Immediate ATP stores  STRUCTURE OF ATP AND ADP HOW ATP RELEASES ENERGY HOW ATP RELEASES ENERGY  THE ROLE OF ENERGY COUPLING Coupled Reaction – energy released from one reaction (glucose breakdown) is used to drive another reaction (ATP synthesis). In a coupled reaction, an exergonic reaction (one that releases energy) is paired with an endergonic reaction (one that requires energy). THE ROLE OF ENERGY COUPLING REVIEW:  REVIEW ATP has three phosphates; when it releases one, energy is released, turning it into ADP. ADP is recharged back into ATP by adding a phosphate group using energy from food. This cycle repeats, enabling continuous energy transfer in the cell. REVIEW ISAIAH 40:31 (NIV): “But those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.” Activity: Creating a Diagram of the ATP-ADP Cycle Instructions: Draw a clear and accurate diagram of the ATP-ADP cycle. Be sure to label each component, including ATP, ADP, phosphate groups, energy release, and mitochondria. Use arrows to show the process of ATP converting to ADP and back to ATP. Write a 4-5 sentence explanation below your diagram. Make sure your explanation is clear. Submit your completed diagram and explanation by the end of class.
