A human cell has a mutation in the gene that encodes the enzyme that generates lactate from pyruvate, rendering that enzyme completely non-functional. Assuming that there is ample glucose present, how would this cell generate energy in the presence of oxygen?
A. Glycolysis coupled with ethanol fermentation B. Aerobic respiration C. Primarily through the break down of proteins into amino acids D. This cell would have no way to generate energy under these conditions because it cannot carry out the reactions needed for glycolysis Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about how cells use multiple fuels to generate energy? How does this relate to the inability of the cell to convert pyruvate into lactate? What other information is related to the question? Choose Answer Do you have all necessary information to determine which products would affect cellular respiration? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
