Inhibitory site
C
Regulatory site
D
Active site
Verified step by step guidance1
Understand the structure and function of enzymes: Enzymes are biological catalysts that speed up chemical reactions. They have specific regions where substrates bind to undergo a chemical transformation.
Learn the definition of the active site: The active site is the region on the enzyme where the substrate binds. It is specifically shaped to fit the substrate, often described as a 'lock and key' or 'induced fit' model.
Differentiate between the active site and other sites: The allosteric site is a separate region where molecules can bind to regulate enzyme activity, but it is not where the substrate binds. The inhibitory site is not a standard term; inhibitors may bind to the active site or allosteric site to reduce enzyme activity. The regulatory site is another term for the allosteric site.
Recognize the importance of the active site: The active site is crucial for the enzyme's function because it is where the substrate undergoes a chemical reaction, leading to the formation of products.
Conclude that the correct answer is the active site, as it is the specific region on the enzyme where the substrate binds and the reaction occurs.
