Energy Systems- Anaerobic energy systems Flashcards
What running event most predominantly engages the ATP-PC system
60m (indoors). 100m (outdoors).
Within what time periods is the anaerobic glycolytic system the predominant supplier for energy
From 8-10 seconds up to 3 minutes
How much ATP is produced within anaerobic glycolysis
2 ATP
Where does anaerobic glycolysis take place
In the sarcoplasm (glycolysis).
What happens to pyruvic acid within the anaerobic glycolytic system and why
It turns into lactic acid due to the lack of oxygen
What enzyme breaks glycogen into glucose
Glycogen phosphorylase
What enzyme breaks glucose into pyruvic acid
Phosphofructokinase
What enzyme breaks pyruvic acid into lactic acid
Lactate Dehydrogenase
True or false, if oxygen is present lactic acid can be converted back into glycogen
TRUE
Why is energy production in the anaerobic oxidative system much quicker than the aerobic glycolytic system
There are fewer reactions
How would you describe the energy yield of the anaerobic glycolytic system
A small energy yield. 2 ATP total
One negative of the anaerobic glycolytic system is the buildup of lactic acid. How does lactic acid affect enzymes
It denatures enzymes. Prevents the rate at which chemical reactions can take place
As percentages, how does energy yielded from aerobic conditions compare to anaerobic conditions
5% of energy comes from anaerobic conditions while 95% comes from aerobic conditions
