Document Summary
Facilitate wanted movements and inhibit unwanted movements; practice. Turns on by releasing excitatory or facilitory neurotransmitters which opens. Calcium binding to c same time: diagram the cross-bridge cycle. Show where the steps important for power production occur. attached to it due to troponin complex (t, i, c). Actin and myosin are in a weak binding state with phosphate and adp causes a series of shape changes so the actin and myosin can bind strongly. Myosin is detached from actin by atp (adp must be released for atp to attach), flips back to 90. If adp is released and no atp attaches you are in a state of rigor where it stys firmly attached. Calcium is on/off mechanism for cross bridge cycle. A fast uses 3 atps for every one cycle of a slow using the same force. Nervous system wants to maintain tension, so if you reduce tension the.
