Enzymes have "specificity." This means that they
A) have a preferred pH.
B) have a preferred temperature.
C) have a particular substrate.
D) are only in certain cells.
E) require ATP and cofactors in order to work properly.
Specificity
The ability of a test or procedure to correctly distinguish those without a disease or condition from those who have it, often referred to in the context of diagnostic testing.
Preferred pH
The optimal acidity or alkalinity level at which an enzyme, organism, or biochemical process functions most efficiently.
Particular Substrate
A specific substance or surface that an enzyme or other active molecule acts upon to facilitate a chemical reaction.
- Acquire knowledge of enzyme operations, their exactness, and the determinants that modify their effectiveness.

Final Answer :
C
Explanation :
Enzymes have specificity in terms of the substrates they catalyze or react with. Each enzyme has a specific substrate, or set of substrates, that it can bind to and convert into products through catalysis. This specificity is due to the shape and chemical nature of the active site of the enzyme, which only allows certain molecules to fit and be acted upon. Enzymes may also have preferred pH and temperature ranges, but these are not necessarily part of their specificity. The presence of enzymes and their specificity is not limited to certain cells or dependent on ATP and cofactors, although these factors may affect their activity.
