Document Summary

>allows for the transfer of energy from exergonic to endergonic enzyme catalyzed/facilitated chemical reactions. >with contraction the myosin atpase hydrolyzes the atp molecule so energy is released for mechanical movement (25%) and remainder as heat (75%) Atp concentration is held relatively stable therefore as muscle contraction continues energy in the form of atp must be regenerated. >(the use of atp and production of atp must be relatively matched in skeletal muscle) Do not have a large supply of creatine phosphate so it does not last for a long time (about 8 seconds) There is only one reaction to generate the atp so it is fast. An anaerobic and or aerobic (oxygen requiring) energy system. Calcium and insulin assist entry of blood glucose in aerobic glycolysis. Ocygen needed for acetyl coa part of system (aerobic glycolysis) Tca cycly with redox reactions (co2 to nadh) and etc w/ electrochemical gradient. >concentration of acetyl coa, odygen, and an electron transport chain enzyme.
