Document Summary
Explain the significance of the first & second laws of thermodynamics. Define free energy and its relationship to the spontaneity of processes. Clarify the distinction between steady state and equilibrium. Explain the concepts of activation energy and transition state. Describe the enzyme kinetic principles and define terms (km, vmax) . To understand how they do this you must understand the flow of energy in a chemical reaction thermodynamics. A living cell 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. Never a loss of energy, just transforms. Chemical energy is converted to mechanical and thermal energy. Energetic events in the universe tend to proceed from a state of higher energy to a state of lower energy. Spontaneous can occur without the input of external energy, thermodynamically favorable.
