Question:
A---enzyme A------>B----enzyme B------>C
Refer to the metabolic pathway illustrated above. If A, B, and C are all required for growth, a strain that is mutant for the gene-encoding enzyme A would be able to grow on medium supplemented with _____.
A) nutrient A only
B) nutrient B only
C) nutrient C only
D) nutrients A and C
Answer:
B) nutrient B only
Explanation:
The mutant has a mutation in the gene that codes for the enzyme A. Therefore, this mutant would not be able to convert the substance A into B. Without the presence of substance B, the final product can not be formed. However, if the mutant is supplemented with the substrate "B", it can convert the B into the final product (substance C). Therefore, the mutant would be able to grow in the medium to which the already prepared substance B has been added.
<h2>Answer:</h2>
The option A is the correct option. The fungi share a mutualistic association with the trees.
<h3>Explanation:</h3>
Mutualism or interspecific cooperation is the way two organisms of different species exist in a relationship in which each individual fitness benefits from the activity of the other. And in this case, both plant and fungi are benefited by each other. The plant provides food and habitat for the living of fungi and fungi, in turn, decompose dead organic matter to provide simple compounds to plants.
While in commensalism only one either plant or fungi can be benefited. And it is also not a parasitic interaction.
