Question

Enzymes that are only produced when substrate is present are termed
A)exoenzymes.
B)endoenzymes.
C)constitutive enzymes.
D)induced enzymes.
E)conjugated enzymes.

Accepted Answer

Induced enzymes are only produced when the substrate is present. They are under the control of regulatory genes that turn on their expression in response to the presence of the substrate. Exoenzymes are enzymes that are secreted outside the cell to break down large molecules, endoenzymes are enzymes that act inside the cell, constitutive enzymes are always present and active regardless of the presence or absence of substrate, and conjugated enzymes are enzymes that require cofactors or prosthetic groups to function.
