Question

Birds in the area have been dying at an unusually high rate and it appears to be due to their ingestion of an invasive species of berries. You isolate a chemical compound from the berries that inhibits ATP synthase, the enzyme responsible for making ATP in the electron transport chain. To further characteristize this new inhibitor you collect the following data:
which of the following statement is correct?
a. the km increased in the presence of the inhibitor.
b. the vmax increased in the presence of the inhibitor.
c. this is a noncompetitive inhibitor
d. thus inhibitor likely binds within the active site of the enzyme.

(4) Birds in the area have been dying at an unusually high rate, and it appears to be due to thelr Ingestion of an Invasive species of berries. You isolate a chemical compound from the berries that inhibits ATP synthase, the enzyme responsible for making ATP in the electron transport chain. To further characterize this new inhibitor, you collect the following data: [inhibitor], in mM Vo, in mM/min -inhibitor Vo, in mM/min +inhibitor 0.2 0.4 0.8 7.5 10.0 10.7 12.5 13.6 3 2.0 3.0 4.0 4.3 5.0 5.5 2.0 4.0 Which of the following statements is correct? (3pts) A. The Kw increased in the presence of the inhibitor. B. The Vmax increased in the presence of the inhibitor C. This is a noncompetitive inhibitor D. This inhibitor likely binds within the active site of the enzyme.

Explanation / Answer

Ans c

This is a non competitive inhibitor .These decrease the Vmax The inhibitor binds to the active site where it is modified by the enzyme to produce a reactive group that reacts irreversibly to form a stable inhibitor-enzyme complex..
