Many of the antiviral drugs currently used to treat HIV/AIDS also interfere with an enzyme that helps mitochondria multiply. Treatment can therefore result in a decrease in the number of mitochondria found in certain tissues. Given this information, what might you expect to see in patients treated with antiviral drugs?
A. An increase in oxidative phosphorylation B. An increase in phosphofructokinase activity C. An increase in NADH dehydrogenase activity D. An increase in lactic acid levels 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 which cellular respiration processes occur in mitochondria? How would a reduction in mitochondria affect the ability of the cell to harvest energy? What other information is related to the question? Choose Answer Do you have all necessary information to determine the outcome on respiration from taking antiviral drugs? 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?
