ATP-PC (alactic) system
Lactate system
Aerobic system
By-products: carbon dioxide and water
High-intensity, moderate duration exercise (e.g. 800 m run)
Used in short duration, high intensity exercise (e.g. Power lifting)
By-product: Lactic acid
Low-moderate intensity exercise (e.g. water aerobics)
Most rapid release of energy
Very limited (~8-12 seconds)
Aerobic reaction takes place in the cytoplasm and mitochondria
Yields 1 ATP molecule per complete reaction
Can only produce energy for up to 4 minutes
Involves the enzyme creatine kinase in the cytoplasm
By-products: ADP + Pi are used in subsequent hydrolysis reaction to yield ATP
Energy released from the reaction is directly used to resynthesise ATP
Involves anaerobic glycolysis in the sarcoplasm
1 Glycogen molecule as a fuel source can yield 2 molecules of ATP
Anaerobic reaction
Involves aerobic glycolysis
The enzyme pyruvate dehydrogenase converts pyruvate
Involves the Krebs cycle
Involves the electron transport chain
1 molecule of Glycogen can yield 38 ATP molecules
The enzyme lactate dehydrogenase converts pyruvate
By-products reduce the pH of the muscle and the blood
Uses Phosphocreatine (PC) as a fuel
Longer recovery needed to remove waste products (up to an hour to remove lactic acid)
Rapid recovery (approximately 10-12 seconds for every second worked)
Can continue almost indefinitely
