Energy systems
Cards in this deck (7)
- 1ATPBody can produce unlimited energy from
throug adenosine triphosphate.
enzyme ATPase breks bond between 2nd and third phosphate which releases aorudn 1-2 seconds - 2ATP-PCUsed to resynthisise ATP lasta round 8 seconds
The body detects exercise through the chemo recptors detecting bicarbonate .
Creatine Kinase is then used to break the bonds between phosphorous and creative. The phosporuous then bodns back with the Adenosine disphopate - 3Advantages of atp-pc systemEvery 1 PCr broken down will procuce 1 ATP
ATP can be resynthesied rapidly
PC systems can be depleted 0 % in 30 seconds
No fatiguing byproducts
Creatine can extend life - 4DisadvantagesLimited PCr stores
Resynthisiation require 02
Can take up to the minutes to refuel - 5Anaerobic lactate systemGlycogne is roken down into glucose by phosphorylase
Glucose is broken down into pyrovate by phospofructokinase
If no oxygen is present the pyrovate recats with lactate dehydrogenase producing lactic acid
Thsi forms 2ATP known as anaerobic glycolosis - 6AdvantagesATP cna be resynthused due to few
chemical reactions
In the presence of 02 lactic acid can be rmeoved
Can be used in a sprint finish - 7DisadvantagesLactic acid by product whcih cuased fatigeu de to low ph denaturing enzymes
only 5% of energy can be released in anaeorbci rocnditions/
