Document Summary

Must understand the needs and provide the right fuel. Potential to do work (measured in calories: a property of matter that changes and is equated to work energy does work. Atp: energy carrying molecule: all bodily cells can utilize atp. Structure of atp: the energy currency that powers all forms of biologic work. Atp can be used for: hormones, nerve transmission, muscle action, circulation, digestion. Without atp you can"t survive none of the following things would function. Adenosine: adenine: no nitrogen, ribose: sugar structure -pentos (5 carbons) Triphosphate: complete form: 3 phosphates, energy between the phosphate bonds, phosphorylation: adding back phosphates if you break a bond release energy atp adp + p amp + p, amp + p adp; adp + p atp. Muscle: atp adp (myosin atpase = catalyst) Myosin atpase in myosin filaments to generate a power stroke to glide myosin and actin and create force.
