The catalytic power of enzymes. Most biological reactions require enzymes. Even simple reactions like the reaction of CO 2 with water to form carbonic acid. This reaction is catalyzed by the enzyme carbonic anhydrase. Carbonic anhydrase is one of the fastest enzymes.
Enzymes are highly specific.
Both in terms of the type of reaction carried out. And the identity of its substrates. Trypsin - cleaves on the carbonyl side of positively charged amino acids. That is arginine and lysine. Chymotrypsin - cleaves on the carbonyl side of aromatic residues.
