Question

A competitive inhibitor: Please choose the correct answer from the following choices, and then select the submit answer button. binds to the active site on the enzyme, blocking substrate molecules from the site. binds to any part of the enzyme, altering its shape, and blocking its ability to bind with substrate. binds to the active site on the substrate, blocking enzyme molecules from interacting with the site. causes destruction of the enzyme, inhibiting the reaction. causes destruction of the substrate, inhibiting the reaction.

Answer 1

Competitive inhibitor

Explanation:

Competitive inhibitor is the one which binds to the active site on the enzyme, blocking substrate molecules from the site

• Competitive inhibitor is a type of reversible inhibitor in which inhibitor binds with enzyme's active site hence inhibitor competes with substrate for binding site
• The activity of competitive inhibitor is overcome by increasing substrate concentration
• In competitive inhibition,the value of Km(Michaelis Menten constant) increases whereas that of Vmax(maximum velocity) remains unchanged
