Question

Compare competitive and noncompetitive inhibition Question Suppose that glycerol (CH,OHCH(OH)CH,OH) is a substrate in an enzyme-catalyzed biochemical reaction and propylene glycol (CH OHCH(OH)CHZ) is an inhibitor of the reaction. Would you expect propylene glycol to be a competitive or noncompetitive inhibitor? Why? Select the correct answer below: O It is likely that propylene glycol would be a competitive inhibitor because it easily binds to glycerol. O It is likely that propylene glycol would be a competitive inhibitor because it has a structure that is similar to glycerol. O It is likely that propylene glycol would be a noncompetitive inhibitor because it has a structure that is not similar to glycerol. 0 It is likely that propylene glycol would be a noncompetitive inhibitor because it does not readily bind to glycerol.

Answer 1

question 1

It is likely that propylene glycol would be a competitive inhibitor because it has structure similar to Glycerol.

In competitive inhibition inhibitor competite for the active site of enzyme because inhibitor is structurally similar to the original substrate.

Question 2

Enzyme works efficiently at optimum pH.

Changing pH reduces its activity.

This is because, on changing pH the tertiary structure of an enzyme is affected.

The tertiary structure of an enzyme is formed by Hydrogen bonds and and ionic bonds of R groups of different amino acids, changing pH break these bonds causing change in tertiary structure of enzyme.
