Aerobic energy system

Question 1

Aerobic glycolysis energy system

Answer 1

• Glycogen is converted into glucose by the enzyme glycogen phosphorylase
• Glucose is converted to pyruvic acid by phosphofructokinase (net gain of 2ATP)
• Pryuvic acid is carried in Aectylcoenzyme A which is combined with Oxaloacetic acid
• Oxaloacetic acid makes citric acid which is then oxidised into the kerb cycle where lots of reactions take place
• The kerb cycle releases carbon dioxide and water
• H+ is carried by Hydrogen carriers down the electron transport chain
• E- split from H+
• This produces enough energy to resynthesise 34 ATP

Question 2

What is the intensity of aerobic glycolysis system

Answer 2

LOW

Question 3

What is the duration of the aerobic glycolysis energy system

Answer 3

3 mins +

Question 4

What is the activity that the aerobic glycolysis system predominantly uses

Answer 4

Phosphofructokinase
Glycogen phosphorylase
Acetyl Coenzyme A

Question 5

What is the fuel for the aerobic glycolysis system

Answer 5

Glycogen and Fats (triglycerides)

Question 6

What is the net gain of ATP of aerobic glycolysis

Answer 6

38 ATP total

2 ATP- Glycolysis
2 ATP- Kreb cycle
34 ATP- Electron transport chain

Question 7

What is the site of the aerobic glycolysis in the body

Answer 7

Mitochondria (matrix and cristol) and Sarcoplasm

Question 8

Advantages of aerobic glycolysis

Answer 8

+ More ATP can be produced- 38ATP
+ There are no fatiguing by products (CO2 and H2O)
+ Lots of glycogen and triglycerides store so exercise can last for a crime
