ATP-PC system Flashcards
1
Q
What is the enzyme?
A
Creatine Kinase
2
Q
What is the fuel?
A
Phosphocreatine
3
Q
When is CK released?
A
Automatically when ADP concentrations increase
4
Q
Where is the site of reaction?
A
Sarcoplasm
5
Q
Describe the process
A
PC broken down by CK to form P + C.
P + ADP + Energy = ATP
6
Q
What is the yield?
A
1:1
7
Q
What is the type of reaction?
A
Anaerobic
8
Q
What are the by-products?
A
None (harmful)
9
Q
How long does the system provide energy for?
A
3-10 seconds
10
Q

11
Q
Give three disadvantages
A
