This is an example of:
Correct Answer: Competitive inhibition
Description: Competitive Inhibitors:
In competitive inhibition, the inhibitor (I) binds to the substrate-binding portion of the active site thereby blocking access by the substrate.
The structures of most classic competitive inhibitors, therefore, tend to resemble the structure of a substrate, and thus are termed substrate analogs.
Inhibition of the enzyme succinate dehydrogenase by malonate illustrates competitive inhibition by a substrate analog.
Key Concept:
Competitive inhibition occurs when the inhibitor binds reversibly to the same site that the substrate would normally occupy and, therefore, competes with the substrate for that site.
