Red blood cells (RBCs) do not contain mitochondria. As a result, they are dependent on glycolysis to generate cellular ATP. All of the following statements about metabolism in RBCs are true EXCEPT:. a. RBCs metabolize ketone bodies for energy production when blood sugar is low.
b. RBCs extract less energy per molecule of glucose than cells with mitochondria.
c. RBCs ferment pyruvate into lactate to regenerate NAD+ for glycolysis
d. RBCs do not consume oxygen when metabolizing glucose

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
