poisons such as potassium cyanide and curare are enzyme inhibitors that interfere with the active site of critical enzymes. We will be working in this lab with a representative enzyme - catalase. Catalase has a molecular weight of approximately 240,000 daltons and contains 4 polypeptide chains, each composed of more than 500 amino acid monomers The reason is that the competitive inhibitor is reducing the amount of active enzyme at lower concentrations of substrate. When the amount of enzyme is reduced, one must have more substrate to supply the reduced amount of enzyme sufficiently to get to Vmax/2. It is worth noting that in competitive inhibition, the percentage of . Introduction (10 points) a) In lecture we discussed the structure of a protein and how this relates to enzyme function

Alanine Aminotransferase (ALT; also called SGPT) The effect of variable catechol concentration on the rate of enzyme activityNiloufar KosariLab Partners: Weiwei Liu, AshkaanLab Section: 1219Date: June/2/2013 IntroductionEnzymes are biological molecules that are involved in chemical interconversions in living organisms. They act as catalysts that greatly accelerate both the rate and specificity of metabolic reactions (Garrette & Grisham, 1999) enzyme kinetics were studied. Two trials of uninhibited reaction over a range of substrate concentrations, while the second was inhibited with 10.0 mM molybdate over that same range of substrate concentrations. In this manner, the extent of the enzyme inhibition was studied, and a mechanism of the inhibition was identified. 0 0.005 0.0
