What is the active site of an enzyme?
The active site is the region of the enzyme where substrate molecules bind and undergo chemical reaction.
The active site is a groove or pocket formed by the folding pattern of the protein..
Only this region of the enzyme binds to the substrate.
The enzyme - substrate complex is a 3 D structure. This together with the chemical properties of the amino acids and co - factors permits only a particular substrate to bind to the site, thus rendering it specific only to certain proteins.
