Document Summary
3 main types: myosin atpase: on myosin head, give power for power stroke, remove head from acin, ca atpase: ca pump on sarcoplasmic reiculum that makes ca taken back up into. Sarcoplasmic reiculum (sr: na/k atpase: acion potenials across membrane, nervous issues and muscles. Our body does not like to get rid of atp, we want to always make more of it and we use water to rebuild. Supply: phosphagen breakdown: fast, intense, lots of energy, using p, non-oxidaive glycolysis: break down cho without oxygen, oxidaive metabolism: needs oxygen to break down cho (at rest, slow) Phosphagen: locaion: cytosol, no oxygen, fuel storage form: phosphocreaine (pcr) its right in acion with broken down atp, na, Glycolyic: locaion: cytosol, no oxygen, fuel storage form: glucose, glycogen, 10 steps, slower, more energy out of fuel, half as fast, makes atp slower but lasts longer, limit: build-up of metabolic by products (lactate)
