Fuelling Muscle Performance Flashcards
1
Q
How do you measure ATP, PCr, lactate etc?
A
Needle biopsy, rapid freezing, carious assays
or
IP nuclear magnetic resonance (NPIR)
2
Q
How is ATP resynthesised by substrate level phosphorylation?
A
PCr + ADP +H+ = Cr + ATP
2ADP = ATP + AMP AMP = IMP + NH3
3
Q
Why is the CPK reaction so great?
A
Temporal buffer for decreased ATP, pH buffer, spaital buffer, Pi stimulates glycolysis, regulates [ADP] and drives Krebs but high Pi induces fatigue,
