Q

When is the breakdown of Creatine Phosphate triggered?

A

By the formation of ADP itself and as soon as exercise states.

Q

Reactions

A

Creatine Phosphate=Creatine + Pi
ADP + Pi=ATP

Together
Creatine Phosphate + ADP=ATP + Creatine.

16
Q

How can creatine phosphate stores be regenerated?

A

From ATP when the body is at rest.

17
Q

Three energy systems

A

ATP/PC System
Anaerobic Respiration
Aerobic Respiration

Allow ATP regeneration.

18
Q

How is exercise sustained for longer periods?

A

Aerobic respiration can regenerate ATP as quickly as it is broken down, this allows exercise to be sustained for longer periods.
