Document Summary

Complex protein architecture > increase rates of biological reactions. To understand how they do this you must understand the flow of energy in a chemical reaction > thermodynamics. A living cells bustles with activity (a cell must acquire and expend energy) Bioenergetics study of energy transformations in a living organism. Energy capacity to do work; change or move things. Thermodynamics study of changes of energy. Conservation of energy > energy can be neither created nor destroyed but can be converted into different forms (=transduction) I. e. chemical energy in atp > mechanical energy as organelle move about cell. Endothermic (delta e>0) reaction that gain heat (requires energy to become) Exothermic (delta e<0) reaction that lose heat (releases energy) Chemical energy is converted to mechanical and thermal energy. Atp > adp = release of energy which can be turned to mechanical energy to allow muscles to move.
