D. It acts as a reactant in a chemical reaction

Explanation:

In biochemistry optics, a substrate is a molecule on which an enzyme acts. In other words, it is up to the enzymes to catalyze chemical reactions involving a substrate. The union between enzyme and substrate forms a complex. In other words, substrate is a substance that will be used by the enzyme to generate another substance, similar to the conductor in a chemical reaction. Therefore we can state that the substrate acts as a reagent in a chemical reaction.
