Enzymes That are Secreted by a Cell to Catalyze Hydrolysis

Question

Enzymes that are secreted by a cell to catalyze hydrolysis reactions are
A)apoenzymes.
B)exoenzymes.
C)constitutive enzymes.
D)regulated enzymes.
E)endoenzymes.

Accepted Answer

Exoenzymes are enzymes that are secreted by a cell to catalyze hydrolysis reactions outside of the cell. They are often used by bacteria to break down complex substances in their environment for nutrient acquisition. Apoenzymes are enzymes that require the binding of a cofactor to be active, constitutive enzymes are continuously produced by a cell regardless of environmental conditions, regulated enzymes are enzymes whose activity is modulated by environmental signals, and endoenzymes are enzymes that catalyze reactions inside of the cell.
