Proteins called enzymes serve as biological catalysts.
Chemical reactions are accelerated by catalysts.
Substrates are the molecules that enzymes can interact with, and the enzyme changes the substrates into other molecules known as products.
Oxidoreductases - Oxidoreductase is an enzyme that catalyzes the oxidation reaction in which electrons tend to go from one form of a molecule to the other.
Transferases - Transferases enzymes aid in the movement of functional groups between acceptor and donor molecules.
Hydrolases - Hydrolases are hydrolytic enzymes that catalyze the hydrolysis reaction by cleaving the link and hydrolyzing it. as well as donor molecules
Lyases - Adds water, carbon dioxide, or ammonia across double bonds or removes these to form double bonds.
Isomerases - Isomerase enzymes catalyze structural alterations in a molecule, resulting in a change in the shape of the molecule.
Ligases - Ligase enzymes are known to charge the ligation process's catalysis.
