Below is a metabolic pathway having 3 chemical reactions and 3 enzymes. Enzyme 1 has 2 binding sites--1 for the substrate A and another for the end product D. As the pathway proceeds, the end product in higher quantities will react with enzyme 1, blocking the enzyme's binding to the substrate. Which statement is true about this pathway? enz1 enz2 enz3 Substrate A --> B --> C --> D end producta. This is a case of noncompetitive inhibition.
b. As a result of the inhibition of the enzyme, there will eventually be less substrate converted to the end product D and this pathway will shut down.
c. Enzyme 1 has 2 binding sites.
d. ALL STATEMENTS ARE TRUE
