The final product of a metabolic pathway may function as a competitive inhibitor. This is known as end-product inhibition, and it enables a cell to regulate a metabolic pathway. The diagram illustrates a metabolic pathway in which the end-product could inhibit enzyme W. What effect would there be if, rather than enzyme W, the end-product inhibited enzyme Z?
- Aquantity of intermediate 1 increase; quantity of end-product decrease
- Bquantity of intermediate 1 increase; quantity of end-product unchanged
- Cquantity of intermediate 1 decrease; quantity of end-product decrease
- Dquantity of intermediate 1 decrease; quantity of end-product unchanged
