BIOL 2021 Lecture Notes - Lecture 16: Enzyme, Activation Energy, Binding Energy
Document Summary
Introduction to enzymes: enzymes are usually proteins (some rna, enzymes are catalysts. Professor christine hrycyna increase the rate of a reaction. Act repeatedly to increase the rate of reactions. Enzymes are often very specific promote only 1 particular reaction. Reactants also called substrates of enzyme rate enhancement. 102-104 fold up to 1020 fold catalyst non-enzymatic (pd) enzymatic: how much is 1020 fold, 3 x 1012 years is 500 times the age of the earth! catalyst yes no time for reaction. Facilitates the transfer of carbon dioxide from tissues to blood and from blood to alveolar air. Decreasing the activation energy of a reaction: lowering the ea increases the rate constant, k, and thereby increases the rate of the reaction. Supply energy by pushing a rock up a hill so that it can slide down the other side, releasing energy. Think of activation energy as the barrier required to make a product.
