Energy Currency of The Body Flashcards
1
Q
What is energy stored in?
A
Adenosine Triphosphate (ATP)
2
Q
What is ATP?
A
Adenosine triphosphate is the energy currency of the body
3
Q
What does separating the bonds between phosphates in ATP cause?
A
An exothermic reaction
4
Q
State the process
A
- Body needs energy
- Enzyme called ATPase is released
- ATPase breaks down ATP into Adenosine diphosphate (ADP) and an inorganic phosphate (Pi)
- Energy is released through an exothermic reaction
- Energy is used for muscular contraction
5
Q
How long does ATP last for
A
2 seconds
6
Q
What happens to ATP when it runs out
A
It resynthesises - ADP and Pi are put back together
7
Q
What are the 3 energy systems?
A
- ATP-PC system
- Anaerobic glycolytic system
- Aerobic system
8
Q
What determines what system is used?
A
The intensity and duration of exercise
