Energy Systems And ATP Resynthesis Flashcards
Where does the ATP-PC system occur?
It occurs in the muscle sarcoplasm.
What type of reaction is the ATP-PC system?
Coupled reaction.
Explain the ATP PC system?
ATP is broken down by ATPase into ADP + Pi (phosphate) + (energy) [exothermic] next…….
PC is broken down by creatine kinase Into Pi (phosphate) + C + energy [exothermic] next…
ADP + Pi (phosphate) + energy combines to synthesise ATP.
What are the 5 advantages of the ATP-PC system?
- It is quick as it has immediate response.
- There are no harmful byproducts.
- We aren’t waiting for oxygen.
- It is used for high power anaerobic exercise.
- PC resynthesises quickly so recovery time is small.
What are the 5 disadvantages of the ATP-PC system?
- It runs out quickly.
- It can only be used around 10 seconds.
- Cannot be used for long distances or aerobic exercise.
- PC storage is limited in muscles.
- Low energy output from input. (1 mol of PC produces 1 mol of ATP).
What reaction is happening in the glycolic system?
Glycolysis.
Where does the glycolic system reaction happen?
In the muscle sarcoplasm.
What simply is the glycolic system?
Breakdown of glycogen into finer components to generate energy.
How many ATP does the glycolic system generate?
2ATP.
How does the glycolic system work?
1.Glycogen found in the muscle and liver is breaking down to become glucose by the enzyme GPP.
2. glucose is broken down into pyruvic acid by the enzyme PFK.
3. Pyruvic acid is then broken down into lactic acid by LDH and releases the 2 ATP.
What are the 4 advantages of the glycolic system?
- There’s no waiting for oxygen.
- It can be used for anaerobic exercise.
- It resynthesises quickly.
- There is more energy energy made for ATP to be broken down.
What are the disadvantages of the glycolic system?
1.There is a byproduct of lactic acid.
2,There is a limited time of use.
