Energy Systems Flashcards
What enzyme breaks glucose into pyruvates?
Phosphofructokinase. (PFK)
What enzyme breaks pyruvates dow to lactic acid?
Lactate Dehydrogenase (LDH)
What type of performer would use the ATP-PC energy system?
A 100m sprinter or Javelin thrower.
What type of performer would use the Anaerobic Glycolytic energy system?
A 400m sprinter or a 200m swimmer.
What type of performer would use the Aerobic energy system?
A marathon runner or a road cyclist.
Define glycolysis.
When glucose is converted to pyruvate to produce energy.
What is sarcoplasm?
The fluid that surrounds the nucleus of a muscle fibre and is where anaerobic respiration takes place.
How does the ATP-PC system work?
PC > Pi + C + energy
Energy > Pi + ADP > ATP
How long can the ATP-PC system last for?
10 seconds
How much ATP is created from the ATP-PC system?
1.
How long does the anaerobic glycolytic system last for?
3 minutes but can peak at 45 secs.
Name the three parts of the aerobic energy system.
Glycolysis, Krebs cycle, Electron transport chain.
How much ATP is gained from the first part of the aerobic system?
2 ATP molecules.
How much ATP is gained from the second part of the aerobic system?
2 ATP.
How much ATP is gained from the third part of the aerobic system?
34 ATP molecules.
