Deck 2 - Aerobic Energy System Flashcards
State the three energy systems
The aerobic oxidative system, anaerobic glycolytic (lactic acid) and ATP-PC
What system is used when intensity is low and duration long
Aerobic oxidative system
Name the three stages of the aerobic oxidative system
Glycolysis, The Kreb Cycle and The Electron Transport Chain
Where does glycolysis within the aerobic oxidative system take place
The sarcoplasm
How many ATP are produced within glycolysis of the aerobic oxidative system
2 ATP
Glycolysis is the breakdown of glucose in to what acid
Pyruvic acid
During glycolysis within the aerobic oxidative system, oxygen is present so pyruvic acid is converted into what
Acetyl Coenzyme A
What happens to pyruvic acid if oxygen is not present within glycolysis
It forms lactic acid
What percentage of energy yield is contributed by protein
15%
Where is glycogen stored
Muscles and liver
Where do the second and third stages of the aerobic oxidative system take place
Mitochondria
Name the 4 things produced in The Kreb Cycle
Water, carbon dioxide, 2 ATP and hydrogen ions
Of the four things produced in The Kreb Cycle, which one enters The Electron Transport Chain
The Hydrogen Ions
How much ATP is produced in The Electron Transport Chain
32-34 ATP
How much ATP is produced overall in the aerobic oxidative system
36-38 ATP
What is the name given to the breakdown of stored fat
Beta Oxidation
True or false, one positive of the aerobic oxidative system is that there is not fatiguing by-products
TRUE
As a percentage, how much more oxygen is required to break down a molecule of fat, compared to glucose
15%
How would you describe the energy yield of the aerobic oxidative system
Extremely high energy yield. This is a positive of this system
Describe the speed that energy is produced within the aerobic energy system
This system has a slow speed of energy production. It can take minutes for this system to produce energy. It is not rapid. This is a negative
What running event most predominantly engages the anaerobic glycolytic system
400m running
What running event most predominantly engages the aerobic oxidative system
Marathon running
