Energy for exercise
Glycolytic systems
aFTER pc stores deplete and ATP levels fall, ADP levels rise again = triggers release of phosphofructokinase, which catalyses the breakdown of the next available fuel - glucose.
-
-
if no o2 is available, pyretic acid and lactate dehydrogenase is release. LHD catalyses the conversion of pyvuric acid to lactic acid
-
-
Strength - large fuel stores in liver and muscle, Fast, provides energy for high intensity up to 3 mins
neg - fatigue due to lactic acid, low ATP yield, recovery is long
ATP- PC
- ATP levels drop and ADP + p levels rise. This triggers the release of creatine kinase, enzyme which catalyses the breakdown of the next available fuel phosphocreatine.
- phosphocreatine is a simple structure which can be broken down anaerobically in sarcoplam by creatine kinase, releasing ATP resynthesis. This forms a coupled reaction. This happens quickly as both are simple structures, providing energy for high intensity activities eg high jump, 100m sprint
-
strengths - PC readily available in muscle cell, simple and rapid breakdown, no fatiguing by products
-
Electron transport chain
-
-Hydrogen ions are oxidised , releasing H2O
-
-
-
-
ATP
Made up of one adenosine molecule and 3 phosphate groups held together by high energy phosphate bonds
-
Krebs cycle
Acetyl CoA combines with oxaloacetic acid to create citric acid. this is oxidised, Co2, hydrogen and 2 moles ATP is released. Co2 is released as a bi- product and hydrogen atoms removed by NADS and FADS.
-
Aerobic systems - Aerobic glycolysis, Krebs cycle, Electron transport chain
Advantage of aerobic systems - good supply o2, large ATP resynthesis, no fatiguing by products
NEG - more complex, slower rate, need more o2 supply
