Lactate Anaerobic System

Question 1

What is the process of glycolysis

Answer 1

1 - glycogen broken down into glucose
2 - glucose is broken down into pyruvic acids via the enzyme phosphofurctokinase
- 2 ATP molecules are gained
4 - pyruvic acid is converted into lactic acid via the enzyme lactate dehydrogenase

Question 2

When does performance peak during this system

Answer 2

Around 45 seconds

Question 3

What are the advantages of the lactate anaerobic system

Answer 3

• any lactic acid that accumulates can be converted back into pyruvate via the cork cycle
• ATP can be resynthesises quickly as their are few chemical reactions

Question 4

What are the disadvantages of the lactate anaerobic system

Answer 4

• accumulation of lactic acid
• only 5 percent of energy within glycogen can be released anaerobically, the other 95 percent is released in the presence of oxygen
