B
Uncompetitive inhibitor
C
Non-competitive inhibitor
D
Allosteric inhibitor
Verified step by step guidance1
Understand the role of an enzyme's active site: The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
Identify the characteristics of a competitive inhibitor: A competitive inhibitor is a molecule that resembles the substrate and competes for binding to the active site of the enzyme.
Differentiate between types of inhibitors: Competitive inhibitors bind to the active site, while uncompetitive inhibitors bind to the enzyme-substrate complex, and non-competitive inhibitors bind to an allosteric site, not the active site.
Consider the effect of a competitive inhibitor: Since it binds to the active site, it prevents the substrate from binding, thereby inhibiting the enzyme's activity.
Conclude that the type of inhibitor that binds to the active site, preventing substrate binding, is a competitive inhibitor.
