You identify a mutant strain that doesn't grow in normal medium, but does grow in medium supplemented with Q, indicating that it has a defect in one or more enzymes in this pathway. This strain is also able to grow if you supplement the medium with Y. Which enzymes can you say with certainty are still functional (i. e. not disrupted by the mutation)

the correct answer is E5

Explanation:

the questionnaire is incomplete, the graph with the missing problem is attached and the requested is answered.

We observed in the exercise that obviously the organism has difficulties to grow when compounds X, Y, Z and P are found, however when compound D is found it can develop, so enzyme E5 will be the enzyme of the organism and the one in charge of transforming D in Q, with E5 being functional in nature
