Energy Systems- ATP-PC System Flashcards
1
Q
When ATP levels fall, which enzyme does it activate
A
Creatine kinase
2
Q
Describe the process of the ATP-PC system
(Give the energy yield)
A
1.Phosphocreatine in broken down, by the enzyme creatine kinase, into phosphate, creatine and energy (1 ATP)
2. The phosphate and energy are reacted with ADP to resynthesis ATP
3
Q
Where does the ATP-PC system take place
A
Sarcoplasm
4
Q
Advantages of the ATP-PC system
A
High/Very high intensity exercise
No fatiguing bi-products
No delay for oxygen delivery
5
Q
Disadvantages of the ATP-PC system
A
Low energy yield
Short duration
