Question

Determine the type of inhibition that has occurred in a first order Michaelis-Menten enzyme catalyzed reaction that has yielded the following data. Vi is the velocity in the presence of inhibitor, V is the velocity when run without inhibitor and [S] refers to the substrate concentration. [S] V Vi 5.00 0.29 0.16 1.25 0.27 0.15 0.45 0.23 0.13 0.22 0.19 0.10 0.13 0.14 O.08 Uncompetitive No inhibition at all O None the above ONon-competitive O Competitive

Answer 1

Hi,

Hope you are doing well.

Here from the given data we can see that the speed of reaction in the presence of inhibitor is almost directly proportional to the substrate concentration which means that the given type of inhibition is an 'Competitive inhibition'.

So the correct option is Option 5: 'Competitive inhibition'.
