Increasing the product concentration

James: Are you sure that increasing the concentration of the product will increase enzyme activity? I remember that increasing the concentration of the product can lead to feedback inhibition, where the product binds to the enzyme and decreases its activity. Is that right, Prof.?

Prof. Wilson: That’s right, this is a regulatory mechanism to prevent the overaccumulation of the product. Let’s give it another try!

Which factor can increase enzyme activity?
