Aerobic system Flashcards
How long does this system last?
1-2 minutes
What are the three stages?
Aerobic glycolysis
Kreb cycle
Electron transport cycle
Is o2 present?
at onset of exercise but not enough to keep up with demand
What systems are used for immediate energy production?
alactic system
lactic acid system
what happens to the glucose molecule?
broken down into its simplest form of co2 and water and releases most amount of energy
where does aerobic glycolysis take place?
sarcoplasm
how much energy does it produce?
2 ATP
what is aerobic glycolysis similar to?
like anaerobic glycolysis but due to presence of o2 , no lactic acid was produced
where does the kreb cycle take place?
pyruvic acid diffuses to the matrix of mitochondria
what happens in the matrix of the mitochondria ?
pyruvic acid is broken down to 2 carbon compound acetyl groups
what does acetyl groups combined with?
co enzyme A , to become acetyl coa
what comes with acetyl coe to form citric acid?
oxaloacetic acid
during this cycle what important things occur?
co2 is formed
hydrogen is removed
sufficient energy is released to synthesis 2 atp molecules
oxaloacetic acid has been reformed, can be reused , therefore enters cycle again ( the regeneration of oxaloacetic acid makes this a process)
what is the third stage known as?
Electron transport system
what happens during electron transport system?
hydrogen ions removed. transported by co enzyme to critea of mitochondria , then enters the electron transport system.
