Verified step by step guidance

Understand the role of enzymes in biochemical reactions: Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Learn the terminology: The molecule that an enzyme acts upon during a chemical reaction is called the 'substrate.' The substrate binds to the enzyme's active site, forming an enzyme-substrate complex.

Differentiate between related terms: A 'product' is the molecule formed after the enzyme catalyzes the reaction. An 'inhibitor' is a molecule that decreases enzyme activity, and a 'cofactor' is a non-protein molecule or ion that assists enzyme function.

Visualize the process: The substrate fits into the enzyme's active site like a key fits into a lock, initiating the reaction. This specificity is crucial for the enzyme's function.

Apply the concept: When asked about the molecule an enzyme acts upon, the correct answer is 'substrate,' as it is the starting material for the enzyme-catalyzed reaction.
