Which of the following statements regarding the energy production roles in different environments is incorrect?
|All organisms must generate energy from the nutrients they obtain, typically through the oxidation of organic carbon to generate usable energy in the form of ATP.|
|In glycolysis, glucose is oxidized to pyruvate, which generates two ATP and 2 NADH molecules.|
|In the presence of oxygen the pyruvate can be further oxidized to generate even more ATP via respiration.|
|In the absence of oxygen, further oxidation of pyruvate cannot occur and instead the pyruvate is converted to a waste product like creatinine at the expense of the NADH produced during glycolysis.|
|All of these statements are correct.|
In a complementation test involving 4 monogenic recessive mutants with the same phenotype, a, b, c, and d, only these two crosses: a X b and c X d produce the F1 progeny that do not resemble wild type, while all other crosses do. What conclusion is correct?
A. These mutants represent only one gene
B. These mutants represent 2 genes
C. These mutants represent 3 genes
D these mutants represent 4 genes
E. The information is not sufficient to draw a conclusion.
