A Lab Recently Developed a New Drug Which Is Hypothesized

question 52

Multiple Choice

A lab recently developed a new drug which is hypothesized to inhibit the enzyme cyclooxygenase-2 (COX-2) and reduce inflammation.In their first test they monitored the reaction of substrate as it is converted to product in the presence of the new drug (data shown below) .If the hypothesis is correct the observed initial rate will be at least 2 times slower than the normal reaction without the drug.If the normal initial rate is 30 mM/s, does the data below indicate that the team has designed a successful inhibitor?

• A)Yes.
• B)No.
• C)This cannot be determined with the information given.
• D)The data is dependent on the maximal velocity.
• E)The answer is dependent on the substrate concentration.
