what was the effect of an inhibitor on enzyme activity?

Answer 1

A competitive inhibitor competes for the active site and temporarily prevents the entry of substrate and thus lowers the velocity of enzyme-catalyzed reactions.
A non-competitive inhibitor binds to another site of the enzyme such that the geometry of the active site is altered and the substrate does not get a better fit. Hence there is no catalysis.

Answer 2

An inhibitor stops or slows down enzyme activity.

Answer 3

An inhibitor would slow or stop the action normally performed by an enzyme.

Answer 4

Beside the question of the form of the inhibition, i could desire to show something with regard to the consequences of metallic cations on hydrogen peroxide itself. The hydrogen peroxide bleaching of fibres interior the production of CTMP (chemi-thermo mechanical pulp) in paper marketplace is strongly suffering on the inactivation of oxidative results of H2O2 via metallic cations (which could be chelated away till now the bleaching reaction). i think of that this could be taken into consideration whilst estimating the enzymatic activity on the foundation of bubble production on your test. the answer of your unique difficulty approximately inhibition could be got here across in case you verify the consequences of Pb+2 on the two the chemical bonding in the back of the three-dimensional shape of the enzyme and the catalytic internet site of the enzyme. My chemical study have taken place at 70' and the two my detrimental reminiscence and the shortcoming of the recent information approximately recent enzyme study avert me that can assist you in a greater detailled way, i'm sorry. good success, even though, to locate the respond!
