Question

\fingertipase\ had a special structure, as do all enzymes, that matches which part of the cell to catalyze the reaction?
inactive sites
substrate
inhibitors
byproducts

Explanation:

Enzymes have a specific structure that allows them to bind to and act upon a particular molecule called the substrate to catalyze a reaction. Inactive sites are non - functional areas, inhibitors slow or stop enzyme activity, and byproducts are the results of the reaction.

Answer:

substrate
