anaerobic glycolysis cause of fatigue
lactate build up in muscles`
Does anaerobic glycolysis require oxygen?
no
ATP-PC requires oxygen?
no
aerobic glycolysis duration
3+ mins
aerobic glycolysis fuel
glucose, sometimes fat and minimally protein
aerobic glycolysis intensity
low intensity
aerobic glycolysis amount of energy produced
38ATP
aerobic glycolysis by-products
water and CO2
aerobic glycolysis recovery time
24-48 hours for fuel to be restored
`aerobic glycolysis cause of fatigue
this system becomes less efficient and fatigued when it has to use fats as a source of fuel rather than glycogen however it is still able to produce ATP so it is not entire fatigued.
aerobic glycolysis need oxygen?
yes
the interplay of energy systems
do this later
3 steps of aerobic glycolysis
aerobic glycolysis, krebs cycle, electron transpot chain
what is the krebs cycle
do this later
what is the electron transport chain

how does resynthesis occur
When the high energy phosphate bond of ATP is broken, ATP turns to ADP. ADP can be resynthesised using the phosphate molecule off PC (phosphocreatine) it joins onto the ADP, creating ATP again.
3 sports which the ATP-PC system is used for
weightlifting, 100m sprint, long jump
3 sports which the anaerobic glycolyisis system is used for
400m run, 100m swim, basketball
3 sports which use aerobic glycolysis
long-distance swimming, marathon, cycling
