Verified step by step guidance

Understand the concept of an enzyme's active site: The active site is a specific region on the enzyme where the substrate binds and the chemical reaction is catalyzed. It is highly specific to the substrate due to its unique shape and chemical properties.

Eliminate incorrect options: Analyze each option provided in the question and determine whether it aligns with the function of the active site. For example, anchoring the enzyme to cellular membranes is not a function of the active site.

Focus on the correct function: The active site is not a storage site for cofactors or responsible for the enzyme's tertiary structure stability. These functions are unrelated to the active site's role in catalysis.

Identify the correct answer: The active site binds specifically to the substrate and catalyzes the chemical reaction. This is the primary role of the active site in enzymatic activity.

Review the importance of specificity: The active site is designed to interact with a specific substrate, ensuring that the enzyme catalyzes the correct reaction efficiently. This specificity is a key feature of enzyme function.
