On what basis are enzymes classified and named?
a.
the gastric juices they secrete
b.
the types of bacteria they kill
c.
the types of antibodies they produce
d.
the types of reactions they catalyze
e.
the coenzymes they originate from

Enzymes are classified and named according to the types of reactions they catalyze.

Explanation:

According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.

Based on the reactions:

Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc

Electron transfer reaction: Oxidases and dehydrogenases

Radical transfer reaction: Transglycosidases, transaminases, etc

Splitting or C-C bond formation: Desmolases

Structural or geometrical change: Isomerases

Hydrolysis of phosphate bonds to join molecules: Ligases

Based on the general principle of recommendations, enzymes are suffixed with –ase  depending upon the catalytic reaction and substrate.
