Lipitor: HMG-CoA reductase, inhibits a liver enzyme that is important in biosynthesis of cholesterol (>$100 billion total sales since 1996).. Viread & Emtriva: reverse transcriptase inhibitors, anti-retrovirus (HIV).. 1 In this exercise we will look at the catalytic behavior of enzymes. You will use Excel to answer the questions in the exercise section. At the end of this session, you must hand in answers to all Regulation of enzymes Introduction andProperties of Enzymes Enzymes are characteristics to facilitate the Enzyme-catalyzed reactions take place Reactants need to pass over the energy barrier, Catalys Drill:. . What background knowledge do you have on enzymes?. Enzyme Structure and Function. Enzymes are . protein catalysts. They speed up the rate at which reactions occur. Lower the activation energy by creating a microenvironment that is energetically more favorable for a reaction. A. . Activation Energy:. 1.. . All the reactions that proceed from initial substrates (initial state) to products (final state) consume energy. This is called free energy of the reaction.. 2.. However the substrates do not become products directly, but must be energized (absorb energy) to reach an activated or transition state. This energy is called activation energy..
