Question

You are studying a type of yeast that can grow in both the presence and absence of oxygen using normal metabolic pathways (glycolysis, Krebs cycle, ETS, ATP synthase). You have generated a mutant that grows well in the presence of oxygen, but not in its absence. You do a stude where you look at the relative levels of NADH in both the mutant and wild-type yeast in the presence and absence of oxygen, and you get the following data:

In no more than 3 sentences explain why there are normal levels of NADH in both the wild-type yeast and the mutant yeast in the presence of oxygen (black bars)

Explanation / Answer

There are normal levels of NADH in both wild type yeast and mutant yeast in the presence of oxygen because both the types of yeast strains have the ability to grow under aerobic conditions. In the presence of oxygen, both the mutant and wild type strains have the same metabolic conditions( glycolysis, Krebs cycle, ETS) and operate similarly.
