What name is given to the reactants in an enzymatically catalyzed reaction? a) active sitesb) reactorsc) EAd) productse) substrate

Substrate.

Explanation:

Chemical reactions may be defined as the reactions in which the reactant is converted into the product. The new substance will always form at the end of the chemical reaction.

The enzymes are required for the biochemical reaction. The reactant is named as substrate in these reactions. The substrate combines with enzyme to form enzyme - substrate complex and its further converted into the product at the end of reaction.

Thus, the correct answer is option (e).

e) Substrate

Explanation:

It is a substance that an enzyme acts on, it is a reactant that results in a certain product after it has been acted on. It binds to the enzyme active site, forming an enzyme-substrate complex.
