Document Summary
Fatty acids from triglycerides can also be used, and may become a source of energy during sustained excercise ( because brain needs atp specifically) *beta oxidation breakdown* The connection between sarcolemma deporlaization following release of acetylcholina at the neuromuscular junction, the release of ca from the sr, binding to troponin, change in config of tropomyosoin exposing myosin-binding sites. Myosin molecule is primed and ready to go due to previosuly bound atp that is hydrolyzed. Gets locked into myosin molecule (hinge and rod like part) once myosin attaches to actin movement of hinge occurs and energy for that was derived from myosin head group hydrolyzing atp. 1from creatine phosphate- muscle stores this and can provide first 10 seconds of activity. Creatine phosphate in muscle binds to adp formed from atp hydrolysis and swaps phospahtes basically which forms atp. creatine phosphokinase cpk phosphogen system. 2 glycolysis- refers just to glucose ( getting atp from glucose from glycolysis).
