ppt 2: Second class discussion of our proteins and projects. Describe the reaction your protein carries out. Focus on the energetics, the free energy difference between reactants and products under standard conditions and in the cell. What forces are most important in helping your protein work. What's the input energy that drives the reactions in your protein? Second presentation template.
