An example of competitive inhibition of an enzyme is the inhibition of:
Options
- Asuccinic dehydrogenase by malonic acid
- Bcytochrome oxidase by cyanide
- Chexokinase by glucose-6-phosphate
- Dcarbonic anhydrase by carbon dioxide.
Correct answer
A. succinic dehydrogenase by malonic acid
Step-by-step solution
An example of competitive inhibition of an enzyme is the inhibition of succinic dehydrogenase by malonic acid. It is the simple type of competitive inhibition. A competitive inhibitor resembles the substrate and binds to the active site of the enzyme. The substrate is then prevented from binding to the same active site.
