ATP-PC System Review (AOS 2 - Energy System)

The ATP - PC energy system produces ____________________ by breaking down ____________________ to resynthesises ____________________ ____________________ . ATP is ____________________ through ____________________ reactions that do not require ____________________ .

The ____________________ of ____________________ stored in muscles is ____________________ to ____________________ seconds ____________________ . PC , like ATP , is stored in ____________________ cells and contains ____________________ ____________________ which provides ____________________ amounts of ____________________ .

PC is ____________________ into ____________________ and ____________________ ____________________ , this provides a ____________________ to ____________________ of ____________________ .

ATP and PC are stored within ____________________ and don't ____________________ on ____________________ to be created in the ____________________ term . Energy released by the ____________________ - ____________________ system does wear out very ____________________ , after only ____________________ to ____________________ seconds of ____________________ physical activity .

PC is ____________________ within ____________________ minutes of the activity ____________________ and a ____________________ recovery being undertaken .

Therefore , the ____________________ - ____________________ system provides the ____________________ rate of ATP release for energy because it depends on ____________________ and ____________________ chemical reactions and ready ____________________ of ____________________ in the muscles . It can only be replenished when there is sufficient energy in the body and this usually occurs through the aerobic pathway or during recovery once the activity is stopped .
