Document Summary

The enzyme involved in the hydrolysis of atp is atpase! We use up our source of atp in about 2 seconds - we need to generate it asap! Fuel storage form: glucose and glycogen, fa/tg, aas! We use this source if we can, but sometimes its too slow! inside the muscle bre in the cytosol is the cbs, surrounded by the sarcolemma! As the cbs move they use atp, produces adp! The production of adp is key, as soon as the enzymes sense more adp than normal, this triggers a variety of different metabolism pathways! To regenerate atp we call on our three systems! Oxidative: greater than 10 reactions, fuel is being produced in the mitochondria and must be transferred out into the cytosol. Also, fuels need to be sent to the mitochondria so we can use them. Energy systems: rate vs duration of atp supply!
