When a _____inhibitor molecule binds to an allosteric site on an enzyme, the shape of the active site changes so that the substrate molecules can no longer fit.

A. Desiccation: Desiccation means drying out or removing water from a material or cell; this term directly names the general process of moisture removal.

B. Flash freeze: Flash freezing freezes a sample rapidly to preserve it, which does not remove moisture (it converts water to ice).

C. Lyophilization: Lyophilization (freeze-drying) removes water by freezing the sample and then sublimating ice under vacuum; it is a specific dehydration technique but not the general term.

D. Pasteurization: Pasteurization uses mild heat to reduce microbial load but does not primarily refer to removal of moisture.

E. Sterilization: Sterilization denotes elimination of all viable organisms, not specifically the act of removing moisture.

A. In mitochondria:
Mitochondria are intracellular organelles in eukaryotes where many metabolic reactions occur, but exoenzymes are secreted enzymes that act outside the cell rather than inside organelles.

B. Within the cell membrane:
Some enzymes are membrane-associated and act at or through the membrane, yet exoenzymes are secreted beyond the cell surface to act on extracellular substrates.

C. In lysosomes:
Lysosomes contain hydrolytic enzymes that function inside the cell to digest materials; exoenzymes operate outside the cell rather than within intracellular digestive organelles.

D. In cytoplasm:
Cytoplasmic enzymes catalyze intracellular reactions; exoenzymes are exported and function extracellularly.

E. Outside of the cell:
Exoenzymes are secreted by the cell into the external environment (or into host tissues) where they break down large molecules into smaller units the cell can transport or where they contribute to pathogenicity.
