The role of the active site of an enzyme

Webb23 apr. 2013 · Enzyme compounds are three-dimensional molecules that have special bonding areas called active sites. At the active site of some enzymes, large molecules are broken into smaller molecules (catabolism). Other enzymes bond small molecules together to make larger compounds (anabolism). The molecules an enzyme metabolizes are … Webb29 maj 2024 · One role that metal ions play in the active site of enzymes is to stabilize the charges that may be present. For example, the enzyme carbonic anhydrase, which plays the vital role of assisting the transport of carbon dioxide in the blood, is a metalloenzyme that includes zinc ions, Zn 2+ .
