Verified step by step guidance

Understand the structure of an enzyme: Enzymes are proteins that catalyze biochemical reactions. They have specific regions where substrates bind to facilitate the reaction.

Learn about the active site: The active site is a specific region on the enzyme where the substrate binds. It is highly specific to the substrate's shape and chemical properties, allowing the enzyme to perform its catalytic function.

Differentiate between the active site and other regions: The allosteric site is a separate site on the enzyme where molecules can bind to regulate enzyme activity, but it is not where substrates bind for catalysis. Similarly, the regulatory domain and N-terminus are structural regions that may play roles in enzyme function but are not involved in substrate binding.

Relate substrate binding to enzyme specificity: The active site is designed to fit the substrate like a 'lock and key' or through 'induced fit,' ensuring that only specific substrates can bind and undergo the reaction.

Conclude that substrates bind at the active site: Based on the explanation, substrates interact with the enzyme at the active site, which is the region responsible for catalyzing the biochemical reaction.
