Question

Write defination of Active site of enzyme.

Answer 1

Enzymes are proteins which drastically increase the speed of chemical reactions by lowering their activation energy. Enzymes do this by interacting with the chemical reactants – called substrates – in ways that make them more likely to react.

Answer 2

Answer :-

In general terms, an "Active site" can simply be defined as a part of the specific 3-dimensional structure of an enzyme.

Extra Information :-

• An enzyme may consist of more than one active site.

• The active sites of most of the enzymes are located at the points which are very close to the surface of the enzymes.

• The active site serves as a "Lock" into which the reactant substrate gets bound as a "Key", leading to the formation of an "Enzyme-Substrate" (ES) complex.

• The point on the surface of the enzyme where the substrate gets bound to the active site, is known as the "Substrate binding site".
