Answer:
Enzymes are not reactants in a chemical reaction.
Step-by-step explanation:
Enzymes are biological molecules that act as catalysts to facilitate and speed up chemical reactions. While they play a crucial role in promoting reactions, they themselves are not consumed or altered during the process, and thus, they are not considered reactants. Instead, they help reactants (substrates) interact and form products, after which they are available to facilitate more reactions.
Example:
reactant+catalyst--> product +catalyst
