Question

Question 5 Your friend is an amateur mushroom hunter. He accidentally eats an Amanita phalloides "Death Cap" mushroom and becomes very ill. You recall from university that this mushroom is toxic because it contains a aminitin, a noncompetitive inhibitor of RNA polymerase. Which of the following hypothetical treatments (if they were possible) would NOT help your friend? Select all best answers for full credit Injecting more RNA polymerase into his cells. Injecting a drug that binds the enzyme-binding region a aminitin. Injecting a drug that binds the active site of RNA polymerase. Injecting a drug that increases the affinity of RNA polymerase for its substrate. Question 6 Lactate Dehydrogenase (LDH) is an enzyme that converts pyruvate to lactate during glycolysis. This is a universal enzyme and just about all organisms possess a version of it for energy production Which of the following statements is most likely true about this enzyme in marine (ocean-dwelling) fish? LDH from marine fish would likely function more optimally at 37° C. LDH in marine fish is likely to have a different active site than LDH in human. The Knof LDH from marine fish would likely decrease at 37°C. LDH from marine fish is likely to be more flexible than human LDH.

Answer 1

Answer 5. Injecting a drug that bind the active site of RNA polymerase. As it also act like inhibitor.

Answer 6. The km of LDH from marine fish would likely decrease at 37°C.

Answer. 1 Catalase = Enzyme

H2O2 = Substrate

O2 = product

Km = Michaelis menten

V = Reaction rate

[S] = substrate concentration
