ATP-PC System

Start with ATP and movement

The ATP-PC System flowchart is a starting point for following the sequence from ATP breakdown to energy used for movement. It also shows ADP, phosphate and phosphate creatine. Work through the flowchart in order, then use it to check that you can describe the sequence in your own words.

Next, open ATP (Adenosine Triphosphate) & PC. This mind map covers ATP stored in muscles, the action of ATPase and the release of energy for movement. Compare its branches with the steps in the flowchart.

Explore the system's features

The ATP/PC System mind map describes an anaerobic system that does not require oxygen for its reactions. It identifies PC as the chemical fuel and the sarcoplasm of muscle cells as the site of the reaction.

For more detail on how the system operates, use ATP/CP System. Its branches include fuel, ATP production, duration, fatigue, by-products and recovery. The Energy systems mind map also covers fuel, duration, fatigue and recovery.

Use quizzes and flashcards

After studying a mind map, take the ATP-PC System quiz and use your answers to decide which parts of the map to revisit. The Characteristics of the Three Energy Systems flashcards provide prompts on ATP-PC features, including fuel source, intensity and duration. They offer another way to practice recalling the terms covered in the maps.

Connect to Energy Systems

ATP-PC System is a section of the Energy Systems unit in Physical education and sport. The broader Energy systems mind map and the flashcards on the characteristics of energy systems can help you place this section alongside the wider unit material.

Choose a map, follow it with the quiz, and return to the branches you want to study again.
