            Introduction to Metabolism Introduction to Metabolism    Complex substances are broken down for energy, required metabolites, structural components, etc.  Cells must synthesize new complex substances.    Thousands of such reactions are occurring simultaneously in a single cell.

********************************************************  These rxns occur with a minimum of  side  products energy loss  or  undesired  interferences  and at  reasonable  temperatures pH  and pressure .  All of these rxns must be  controlled  or  regulated for optimum efficiency. ******************************************************** *
