Wild- Type Bacteria Can Grow on Minimal Medium

Multiple Choice

Wild- type bacteria can grow on minimal medium. Four mutants that cannot grow on minimal med but can grow on minimal medium supplemented with the nutrient "H" are isolated. It is suspected t metabolites T, P, and A are in the biochemical pathway for synthesis of H, so each mutant is tested f ability to grow on minimal medium supplemented with these metabolites:
A. Mutant 1: can grow on minimal medium supplemented with T, but not P or A
B. Mutant 2: is unable to grow on minimal medium supplemented with T, P, or A
C. Mutant 3: is able to grow on minimal medium supplemented with A or T, but not P
D. Mutant 4: can grow on minimal medium supplemented with T, P, or A.
Which of the following is NOT consistent with this information?

A) Mutant 1 will cause a build up of metabolite A
B) Mutant 4 blocks a step before all the metabolites
C) Mutant 3 blocks the conversion of metabolite P →metabolite A
D) Mutant 3 will cause a build up of metabolite T
E) Mutant 2 blocks a step right before metabolite H
