Question

question 36
the most likely place where an exoenzyme participates in a chemical reaction is _.
a outside of the cell
b within the cell membrane
c in lysosomes
d in cytoplasm
e in mitochondria

Explanation:

Exoenzymes are enzymes that are secreted by the cell and function outside the cell. Lysosomes, cytoplasm, and mitochondria are all intracellular compartments. The cell membrane is part of the cell structure but not the typical site for exoenzyme action. Exoenzymes are meant to act on substrates outside the cell, for example, in the extracellular environment to break down large molecules that the cell can then take up.

Answer:

A. outside of the cell
