You Fill Two Containers with Identical Amounts of Reactants a and B

question 92

Multiple Choice

You fill two containers with identical amounts of reactants A and B and enzymes 1-4. In the reactions shown below, if product D inhibits enzyme 2 and product F is an allosteric stimulator of enzyme 1, what will be the final result if you add extra product D to the second container? (Assume that both containers are given enough time for the reactions to go to completion.)

• A) The concentration of product C will increase and there will be no change in product F concentration compared to the first container.
• B) The concentration of reactants A and B will increase relative to the first container.
• C) The concentration of product F will increase in the second container because more of D is converted back to C.
• D) The concentration of products E and F will both increase in the second container, since D inhibits enzyme 2.
• E) The concentration of product F will increase relative to the first container, since enzyme 2 will have been inhibited from converting as much of C into D.
