Explanation / Answer

In the presence of oxygen the metabolic conditions (glycolysis, Krebs cycle, ETC, ATP synthesis) of both mutant and wild types strains are normal in order to have optimal mitochondrial functionality.

In absence of oxygen, there is increase cytoplasmic NADH that increase the matrix concentration of NADH
