Glycolytic system Flashcards
1
Q
Describe the glycolytic system
A
- Anaerobic reaction
- Glycogen is the fuel used
- Sarcoplasm is the site of reaction
- GPP, PFK and LDH are controlling enzymes
- 2 moles of ATP are produced
- High intensity
- Lasts up to 3 minutes.
2
Q
What are the specific stages of the glycolytic system?
A
- Glucose undergoes anaerobic glycolysis
2. Pyruvic acid/without oxygen –> lactic acid
3
Q
What is the equation for the glycolytic system?
A
C6 H12 O6 –> 2C3 H6 O6
4
Q
What are the advantages of the glycolytic system?
A
- Large fuel stores in liver, muscles and blood stream
- Provides energy for high-intensity activities for up to 3 mins
- Lactic acid can be recycled into fuel for further energy production
- No delay for 02
5
Q
What are the disadvantages of the glycolytic system?
A
- Fatiguing by-product lactic acid reduces pH and enzyme activity
- Relatively low ATP yield and recovery can be lengthy
