Competitive inhibition results in response to:
black age of access to active site
alteration of the shape of active site
blockage of access to the allosteric site
Homework Answers
Answer : The correct option is A (black age of access to active site)
Explanation : Competitive inhibitor competes and binds to the enzyme active site since it is structurally similar to enzymes substrate binds to enzyme active site. When an enzyme that follows Michaelis-Menten kinetics is treated with a competitive inhibitor, its Km increases (affinity towards substrate decreases) and Vmax unaffected. A competitive inhibitor diminishes the rate of catalysis by reducing the proportion of enzyme molecules bound to substrate.
Examples fo competitive inhibition:
1. Melanoate is a competitive inhibitor of succinate for the active site on Succinate dehydrogenase enzyme.
2. Methotrxate is a competitive inhibitor of dihydrofolate for the enzyme Dihydrofolate reductase enzyme.
