Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains why plant cells require sunlight to make organic compounds, according to Gibbs’s theory of free energy? The energy input required for making organic compounds equals the usable energy output of respiration. The energy required from sunlight to start photosynthesis is less than the energy needed from another energy source. The energy required to make organic compounds is always greater than the potential energy stored in these compounds. The energy that a plant absorbs from sunlight is spontaneously transformed into chemical energy because the outputs are more stable.

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?
