Free Energy

(-) exergonic rxn is spontaneous, while a (+) endergonic reaction is nonspontaneous

What are the 6 major classes of enzymes?

Oxireductases, transferases, hydrolases, lyases, isomerases, and ligases

Enxymes use an induced fit model

If it is the lock and key model, it will fit too well and never leave. Hence the induced fit of slightly forcing its energy to change is better so once its work it done, it can leave. However enxymes are not overall changed in a reaction

What are the different ways to regulate an enzyme?

Temperature, pH, Inhibitors or Activators
