Introduction to Enzymes Enzymes Are usually proteins, but some RNA molecules exhibit enzyme activity. They are extremely well suited to their functions. High catalytic power. They utilize a wide range of forces and interactions in carrying out their functions. 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.
