Vernon wonders whether NADPH and ATP should be classified as reactants or as products of
photosynthesis. How should these compounds be classified?
A. As reactants because they are used up by photosynthesis

B. As products because they are generated by photosynthesis

C. As either reactants or products depending on the rate that photosynthesis occurs

D. As neither reactant nor product, because they are recycled instead of made or used up

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?
