Question

The graph below shows the concentration of the reactants and products over time for a biochemical reaction that is catalyzed by an enzyme, which diagram best illustrates how the reaction would be affected if a competitive inhibitor that binds to the endzyme was introduced?

D

Answer 1

concentration, 1 2 3 4 5 6 7 - Time

This graph from the option depicts the best illustration. This is because as the compititive inhibitor will bind to the enzyme concentration of the product formed will gradually stablize. This will happen when the concentration of rectant is equal to less than compititive product.

So, the graph representes the concentration of product and reactant against the time where as the concentration of recatant decreases product formation will be increased but as the compititive inhibitor is added it will compete with the reactant and the product fromation rate will start start decreasing and at a point there will be no formation of product when the concentration of reactant will be very less as compared to compititive inhibitor.
