3. Why was the concentration of catechol in test tube 2 and 4?
Homework Answers
The concentration of catechol was increased in test tubes 2 and 4 to check if the inhibition is competitive in nature. If the increased substrate (catechol) concentration overrides the inhibition by PTU, then the inhibition must be a competitive one.
