Text SolutionText solutionverified iconVerified

The activity of an enzyme is highly specific to the presence of chemicals that bind to the enzyme. When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as competitive inhibitor. Consequently, the substrate cannot bind and the enzyme action declines. The inhibition of succinic dehydrogenase by malonate which closely resembles the substrate succinate in structure is the example of competitive inhibition.
