D
Cofactor
Verified step by step guidance1
Understand the role of enzymes in biochemical reactions: Enzymes are biological catalysts that speed up reactions by lowering the activation energy required for the reaction to occur.
Learn the definition of a substrate: A substrate is the specific reactant that binds to the active site of an enzyme and undergoes a chemical transformation during the reaction.
Differentiate between the given terms: An inhibitor blocks or reduces enzyme activity, a product is the result of the reaction, and a cofactor is a non-protein molecule that assists enzyme function. None of these terms describe the reactant that combines with the enzyme.
Recognize that the correct term for the reactant combining with the enzyme is 'substrate,' as it directly interacts with the enzyme's active site to form an enzyme-substrate complex.
Conclude that the substrate is the correct answer based on its definition and role in enzymatic reactions.
