The aerobic energy system Flashcards
1
Q
What is the most accurate way to test the aerobic system?
A
v02 max
2
Q
Explain the first stage of the system
A
Glycolysis
Glycogen is broken down into glucose with the use of the enzyme PFK
This produces pyruvic acid
2 ATP per molecule of glucose
3
Q
Explain the second stage of the system
A
Kreb's cycle Takes place in mitochondria Fats broken down into fatty acids and converted into acetyl co enzyme A Acetyl co enzyme A fed into Krebs 2 ATP and c02 produced Hydrogen ions removes
4
Q
Explain the third stage of the system
A
Electron transport chain
34 ATP produced and H20
5
Q
How many ATP are produced overall?
A
38
2 from glycolysis, 2 from Krebs, 34 from ETC
6
Q
Explain beta oxidisation
A
Series of steps where 2 carbon atoms are removed from the fatty acid each time
These carbon atoms form acetyl co enzyme A and enters Krebs
