Document Summary

**to be able to do that, each cycle takes one atp to accomplish it. So, to get our big movements, its gonna cost us a lot of atp. Energizing cb **reaching out and pulling (that"s when we use the energy) Atpase pumps for ca+2 (to relax and put calcium back into sr. Still in the cell but no longer in the cytosol. ) Creatine p **use substrate-level phosphorylation (along with glycolysis and. One atp (for every creatine phosphate) if we try to just make atp with this creatine and raise the osmolarity inside the cell relative to outside, water"s gonna go into our cells and it"s going to cause muscle swell. Because of this 1:1 relationship, this cannot be our dominant source but bc it"s a one step process, it"s a nice initial source! Anaerobic (we can make atp without the cell having oxygen) Replenished during relaxation (when we rest, we replenish this amount: 2.
