Chapter 8 An Introduction to Metabolism Organization of the Chemistry of Life into Metabolic Pathways -Metabolism is the collection of reactions that occur in an organism -Aided by enzymes it follows intersecting pathways which may be catabolic (breaking down molecule, releasing energy) or anabolic (building molecules, consuming energy). Forms of Energy -Energy is the capacity to cause change; some forms of energy do work by moving matter -Kinetic Energy is associated with motion -Potential Energy is stored in the location or structure of matter and includes chemical energy stored in molecular structure. The Laws of Energy Transformation -The first law – energy cannot be created or destroyed only transferred or transformed -The second law – states that spontaneous changes, those requiring no outside input of energy, increases the entropy (disorder) of the universe. Free Energy Change G -A living organism’s free energy that can do work under cellular conditions -The change in free energy during a biological process is related directly to enthalpy change
