Energy Systems Flashcards
1
Q
What is ATP broken down into to release energy
A
ADP + Pi (phosphate) + energy
2
Q
What are the 3 energy systems
A
Aerobic system
Anaerobic glycolytic system
ATP-PC system
3
Q
Describe the stages of the aerobic system
A
1.Gloycolysis
glycogen is broken down into energy and pyruvic acid and if there is sufficient oxygen the pyruvic acid is converted into Acetyl CoA (2 ATP)
2.Krebs cycle
Acetyl CoA is then broken down into hydrogen,carbon dioxide and energy (2 ATP) and the hydrogen electrons are fed into the next stage
3.Electron transport chain
The hydrogen ions are oxidised to from water and energy (34 ATP)
