In the Metabolic Pathway Illustrated Below, the Starting Material (SubstrateA

Multiple Choice

In the metabolic pathway illustrated below, the starting material (substrateA ) is converted equally to one of two end products, E or G. Use the diagram of the pathway below to answer the following questions. Letters indicate the substrates and products, and numbers indicate the enzymes. In this pathway, the intermediate, C, is a substrate for both enzyme 3 and enzyme 5 and is converted with equal efficiency to D and F.



If end product E inhibits enzyme 1, which of the following would you expect to observe?

A) an increase in the production of G
B) a decrease in the production of E, but no change in the production of G
C) a decrease in the production of E and G
D) an increase in the production of A
