Why is the active site of an enzyme important to enzyme activity?
A
It is the region that determines the enzyme's solubility in water.
B
It is the part of the enzyme that is permanently altered during the reaction.
C
It is where the substrate binds and the reaction is catalyzed.
D
It is the site where inhibitors permanently deactivate the enzyme.
Verified step by step guidance1
Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions in cells without being consumed in the process.
Identify the active site: The active site is a specific region on the enzyme where the substrate molecules bind. This site is typically a pocket or groove on the enzyme's surface.
Explore substrate binding: The active site is crucial because it is where the substrate binds. The enzyme's shape and chemical environment at the active site are complementary to the substrate, allowing for specific binding.
Catalysis at the active site: Once the substrate is bound, the enzyme facilitates the chemical reaction, often by stabilizing the transition state or lowering the activation energy required for the reaction.
Consider enzyme specificity: The active site's structure determines the enzyme's specificity, meaning it will only bind to particular substrates and catalyze specific reactions, ensuring precise control over cellular processes.
