Question

part c - reversible inhibition
you have an enzymatic reaction proceeding at the optimum ph and optimum temperature. you add a competitive inhibitor to the reaction and notice that the reaction slows down.
what can you do to speed the reaction up again?

view available hint(s)

add more inhibitor to speed up the reaction.
add more substrate; it will outcompete the inhibitor and increase the reaction rate.
increase the temperature.
increase the ph

Explanation:

In the case of competitive inhibition, the inhibitor competes with the substrate for the active - site of the enzyme. Adding more substrate will increase the probability of substrate - enzyme binding, thus outcompeting the inhibitor and increasing the reaction rate. In the case of irreversible inhibition, the inhibitor binds covalently to the enzyme, inactivating it, and new enzyme must be added to regain activity.

Answer:

For Part B: The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity.
For Part C: Add more substrate; it will outcompete the inhibitor and increase the reaction rate.
