energy systems Flashcards
How many ATP are produced by the breakdown of glucose during anaerobic glycolysis?
2 molecules
When no oxygen available in the glycolytic system, pyretic acid is turned into what?
Latic acid
what is the maximum time that the glycolytic system can last?
2-3 mins
what are the three stages of the aerobic system
1gycolisis
2 krebs cycle
3 electron transport
how many ATP molecules does the Krebs cycle produce
2 ATP
what is the overall energy yield for one molecule go glucose in the aerobic system
38 molecules
what are the other by products of the aerobic system
water
carbon dioxide
which muscle fibre type is well suited to aerobic energy productions
slow twitch
what do both ATP-PC and glycolytic system not involve
oxygen
where does the ATP-PC and glycolytic system take place
sarcoplasm in muscles
what is the name of the bodies only energy source
ATP
what are the disadvantages of the aerobic energy production
only used for long duration/low intensity
what happens in the electron transport chain
H+ ions being transferred over a membrane this cause the phosphorylation of ADP to form ATP
what enzyme is responsible for breaking the hight energy bond of ATP
ATPase
what is produced from the breakdown of ATP
energy+ADP+PI
how long do muscles store ATP
2 seconds
what is the fuel source for ATP-PC
creatine phosphate
what enzyme breaks down PC
creatine kinase
glucose is broken down into what during aerobic glycolysis
pyruvic acid
what happens in the Krebs cycle
enzyme A is broken down to generate two ATP molecules and also the production of hydrogen and co2
what happens in the glycolysis stage
if oxygen is present pyrucvic acid is converted to acetyl enzyme a and enter kerbs cycle
what are the different energy systems
atp-pc
glycolytic system
aerobic system
