Problem:
Please solve the following question:
Question 1: What concentration of competitive inhibitor is required to yield 75% inhibition at a subrate concentration of 1.5x10^-3 M if Km= 2.9x10^-4 M and Ki= 2x10^-5 M?
Question 2: To what concentration must the substrate be increased to reestablish the velocity at the original inhibitbited value?
Show your calculations, but you do not need to write out any explanation.
