Most protein enzymes catalyze only one specific chemical reaction effectively. what feature of protein structure is most directly responsible for enzyme-substrate specificity

Answer;

d. the specific geometry and types of amino acids in the active site

Explanation;

-Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site.

-For a substrate to bind to the active site of an enzyme it must fit in the active site and be chemically attracted to it. The shape of an enzyme determines how it works. Enzymes have active sites that substrate molecules (the substances involved in the chemical reaction) fit into when a reaction happens.
