roles of phosphocreatines Flashcards
1
Q
how is most atp regenerated
A
from adp during the respiration of pyruvate in the mitchondria
2
Q
what happens in active muscles
A
the demand for atp and oxygen is greater than the rate blood can supply oxygen
3
Q
what does this mean
A
a way of generating atp anaerobically is also needed through phosphocreatine
4
Q
what is phosphocreatine
A
stored in the muscles and act as a reserve supply of phosphate so can combine with adp to reform atp
5
Q
how is the phosphocreatine store replenished
A
using phosphate from atp when muscle is relaxed
