Anaerobic Glycolysis energy system

Question 1

Anaerobic glycolysis energy system

Answer 1

Glycogen
| Glycogen phosphorylase
Glucose
| Phosphofructokinase
Pyruvic acid
| Lactate dehydrogenase
Lactic acid

Question 2

What intensity of anaerobic glycolysis

Answer 2

High

Question 3

What is the duration of anaerobic glycolysis

Answer 3

10 sec - 3 min - Peaks at 1 min

Question 4

What activity does the Aerobic glycolysis predominantly use its energy

Answer 4

400m

Question 5

What enzymes are involved in anaerobic glycolysis

Answer 5

Glycogen phosphorylase
Lactate dehydrogenase
Phosphofructokinase

Question 6

What fuel does the anaerobic glycolysis system use

Answer 6

Glycogen stored in muscles and liver

Question 7

What is the net gain of ATP in the anaerobic glycolysis system

Answer 7

2:1

Question 8

What is the site of the anaerobic glycolysis system

Answer 8

Sarcoplasm

Question 9

Advantages of the anaerobic glycolysis energy system

Answer 9

+ ATP resynthesised quickly- few reactions, lasts longer than ATP-PC
+ Presence of oxygen lactic acid can be converted back to liver glycogen or used as fuel
+ Used for sprint finish- burst of energy

Question 10

Disadvantages of the anaerobic glycolysis energy system

Answer 10

• Lactic acid as the by product denatured enzymes and prevents chemical reactions taking place
• Only a small amount of energy can be released from glycogen under anaerobic conditions 5% (95%)
