1. The enzyme you are studying uses the substrate pictured at right. An inhibitor box in the freezer contains two tubes labeled Inhibitor #1 and Inhibitor #2, along with the structures of the compounds contained within them and their respective Ki. Which one is more likely to be the non-competitive inhibitor? Inhibitor #1 K₁ = 10 μM m CH₂OH OH -0, $ OH OH Inhibitor #2 K₁ = 50 μM Briefly Justify: OH CH₂OH OH OH OH Substrate

What effect will competitive inhibitor have on the apparent Km of an enzyme for its substrate?
pls help me
Choose the correct effect. * increase decrease not change Raising the temperature slightly will... the rate of reaction Boiling temperature will... the rate of reaction Changing the pH toward the optimal pH will... the rate of reaction Introducing a competitive inhibitor will... the rate of reaction
A competitive inhibitor binds to the - active site of theenzyme - a substrate -N termininus of the enzyme -more than one of these
V 23. The graph below is a graph of Vmax (a) Label the graph clearly with both the Vmax and the Km. Estimate the Km from this graph giving the correct units. v/Vmax 1.0 0.5 0.0 0.0 vs [S] for an enzyme. Enzyme Activity vs [Substrate] :0.2 0.4 Substrate (HM): 0.6 (b) If the Vmax = 25 mmoles per minute per µmole of enzyme calculate the Keat and the specificity constant."
3. Enzyme specificity. To determine the specificity of substrate binding for a particular enzyme/protein, structurally related compounds may be used as potential substrates and Km values may be calculated. However, many compounds structurally related to the substrate may bind to the active site but cannot be converted to product. In these instances, the substrate analogs are used as potential competitive inhibitors of substrate binding. Low K, values indicate high affinity of the enzyme for the inhibitor, whereas high K,values indicate low binding affinity. Consider the enzyme xanthine oxidase, which catalyzes the formation of uric acid from the purine bases hypoxanthine or xanthine in humans. The Km for hypoxanthine is 15.0 μM and for xanthine it is 45.0 μM. A few compounds used as competitive inhibitors of the normal substrate hypoxanthine are listed in the table below with their K; values. Comparing the structures of hypoxanthine with the listed substrate analogs, what can you…
