A certain reaction pathway consists of four steps. How would increasing the amount of enzyme that catalyzes in the third step affect the amount of product produced at the end of the pathway?
What will be an ideal response?
Increasing the amount of enzyme at the third step might not affect the whole series of reactions because the rate of the first, second, and fourth enzymes would remain the same. While more substrate would be available for the next step, that doesn't necessarily mean that the fourth enzyme will increase its speed. The net result would be no change if the first, second, and fourth enzymes were working optimally before the change is made. On the other hand, there could be an increase in the amount of product if the first, second, and fourth enzymes were working at below optimum before the change.
