How would anaerobic conditions (when no O2 is present) affect the rate of electron transport and ATP production during oxidative phosphorylation?
A) Electron transport would be unaffected but ATP synthesis would stop.
B) Electron transport would stop but ATP synthesis would be unaffected.
C) Both electron transport and ATP synthesis would stop.
D) Neither electron transport nor ATP synthesis would be affected.

How are viruses and bacteria different?

Using the periodic table, determine which material is most likely a good conductor

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?
