Answer:
Cyanide is an inhibitor.
Explanation:
The cytochrome C oxidase has an active site which is the iron atom. When the cyanide binds to the iron it's inhibiting the enzyme activity, because it's physically avoiding the oxygen (substrate) from binding to the active site. This can lower the enzyme activity or stop it completely.
The glass would work the best.

C. All cells are surrounded by a cell membrane and a rigid cell wall.
Explanation:
All cells have these four parts in common: a plasma membrane, cytoplasm, ribosomes, and DNA. Plasma membrane - also known as cell membrane.That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments. The cell membrane is sometimes also referred to as the plasma membrane.
