In the Fungus Neurospora, a Metabolic Pathway Synthesizes the Amino

question 5

Multiple Choice

In the fungus Neurospora, a metabolic pathway synthesizes the amino acid Z (which is essential for its survival) from the precursor W. The intermediates X and Y are also produced in this pathway. The enzymes E1, E2, and E3 catalyze three reactions in the process, as shown: E1 E2 E3
W → X → Y → Z
X-ray radiation can be used to create a mutant strain of Neurospora that has a defective gene sequence for E2.
Based on this scenario, the mutant strain will survive on media that contain:

• A)only W or X.
• B)only Y or Z.
• C)W, X, Y, or Z.
• D)only X.
• E)only Z.
