1. ATP-PC (ANAEROBIC ALACTIC)
AKA: Immediate Alactic System

2. Learning goals
I will be able to explain the initial energy pathway of the body.
I will be able to connect this pathway to human activity.

3. Three nrg systems
to resynthesize ATP, we simply need to add a phosphate group (PO4 -3) back to the ADP
this process requires E!

4. 1. ATP-PC (ANAEROBIC ALACTIC)
used for high-energy output activities lasting <10 seconds
it’s really fast because it’s really simple:
ATP re-synthesis from PHOSPHOCREATINE breakdown

5. phosphocreatine breakdown provides both reactants required for ATP re-synthesis (phosphate group + E!)
once the phosphocreatine stores are gone (10 seconds), the system stops working until stores can be replenished (which actually requires some ATP)

6. ADP CP ATP C The rxn 1 ATP for every molecule of creatine phosphate
Creatine Kinase + Hydrolysis
ADP CP
ATP C
1 ATP for every molecule of creatine phosphate
The amount of CP in the muscle is limited
During rest, CP levels are restored

7. Which activities use the ATP-PC system as the primary energy source?
sprinting
high jump
diving
weight lifting
shot put

8. provides a quick, intense burst of E! (without producing lactic acid)
