An enzyme is a complex protein folded into a unique three-dimensional shape. Within this large structure is a small, specialized pocket or groove known as the .
The is a three-dimensional cleft or crevice on the surface of an enzyme, typically comprising a small fraction of the enzyme’s total volume (often only 10-20 amino acids). It is not just any hole—it is a masterpiece of molecular engineering. enzyme active site and substrate
The chemical transformation takes place, turning the substrate into the product . Because the product has a different shape and charge, it no longer fits well in the active site and is released. An enzyme is a complex protein folded into
