ACTIVE SITE ON AN ENZYME

  1. Enzymes are comparatively larger in size as compared to the substrates which are relatively smaller.
  2. The active site of an enzyme is defined as a small region at which the substrate binds and participates in the catalysis.
  3. An enzyme has a distinct cleft or cavity in which the substrate is bound.
  4. This cleft contains an active site or active centre in which the amino-acids are grouped together in such a manner so as to enable them to combine with the substrate.
