Verified step by step guidance

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

Clarify the role of the substrate: The substrate is the molecule that binds directly to the active site of the enzyme. This binding initiates the enzymatic reaction, converting the substrate into the product.

Explain the role of cofactors: Cofactors are non-protein molecules or ions that assist enzymes in catalyzing reactions. While they may interact with the enzyme, they do not typically bind to the active site in the same way as the substrate.

Discuss the product: The product is the result of the enzymatic reaction. It is released from the active site after the reaction is complete and does not bind to the active site during the reaction process.

Define allosteric inhibitors: Allosteric inhibitors bind to a site other than the active site (called the allosteric site) to regulate enzyme activity. They do not bind to the active site directly, but their binding can alter the enzyme's shape and affect its ability to bind the substrate.
