a light year is the distance light will travel in a year which is a long long way light travels 186000 miles a second 300000 kilometers per second so a light second is 186000 miles 300000 kilometers
Best Answer: The ATP-PC system is use for around 10 seconds of an event, the ATP is use for 4-6 seconds before the creatine phosphate (CP) provides energy for a further 5 - 10 seconds. Weight lifting is the best example of a sport using the ATP-PC system.
Aerobic energy systemâ simplified biochemistry in the breakdown, release and regeneration of ATP in glycolosis, the Krebs cycle and Electron transport chain, role of mitochondria, use in sporting situations. Anaerobic energy systemsâ simplified biochemistry in the lactate anaerobic system â use in sporting situations.
