In the enzyme-catalyzed reaction shown below, what will be the effect on substances A, B, C, and D of inactivating the enzyme labeled E2? A ---(E1)---> B ---(E2)---> C ---(E3)--->

• A. A, B, C, and D will all still be produced
• B. A, B, and C will still be produced, but not D
• C. A and B will still be produced, but not C or D
• D. A will still be produced, but not B, C, or D
