Question

What is true of a substrate?

A. It is not consumed or change by a reaction

B. It provides a reaction with energy

C. It acts as a product in a chemical reaction

D. It acts as a reactant in a chemical reaction

Answer 1

D. It acts as a reactant in a chemical reaction

Step-by-step 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.

Answer 2

Answer: option D. it acts as a reactant in a chemical reaction.

The substrate is the the chemical species in an organic reaction that reacts to form other product, so the substrate is a reactant. The enzymes can act over specific substrates to accelerate the reaction. While the enzymes are not consumed (they are catalysts) the substrates are consumed.
