Q

PC formula

A

PC->PI+C+Endo energy

Enzyme=creatine kinase

17
Q

What type of reaction is the ATP/PC system

A

Coupled reaction

18
Q

What is taken from each formula to create energy

A 
ATP= ADP
PC= Pi + endo energy
19
Q

Whats phospho creatine

A

High energy compound found in sarcoplasm

20
Q

Sarcoplasm

A

Gel like substance in the muscles which surrounds the muscle fibres

21
Q

How system works

A

When we exercise there is an increase in ADP, which is by product of breakdown of ATP
this increase detected by body and creatine kinsase activated
This enzyme creatine kinase splits phospho creatine into phosphate and creatine and this splitting energy is used to resynthesise ATP from ADP+Pi+ endo energy

22
Q

Advantages

A

No harmful by products
PC resnthesises quickly so recovery time small
High energy
No need for O2

23
Q

Disadvantages

A

PC store in muscles limited, if run out have to move on to next system
Only provides for 10-12 seconds
Low yield

24
Q

How long after using system can we use it again

A

3-5 minutes
