Question
Enzyme inhibition caused by a substrate analog is
Enzyme inhibition caused by a substrate analog is
Open in App
Solution
The correct option is C Competitive
The activity of an enzyme is sensitive to the presence of specific chemicals that bind to the enzyme. When the binding of the chemical shuts off enzyme activity, the process is called as an inhibition and the chemical is called an inhibitor. When the inhibitor closely resembles the substrate in its molecular structure and inhibits the activity of the enzyme, it is known as competitive inhibitor. Due to its close structural similarity with the substrate, the inhibitor competes with the substrate for the substrate-binding site of the enzyme. Such competitive inhibitors are often used in the control of bacterial pathogens.
Thus, the correct answer is option A.
