WebA central example is the entrainment of circadian rhythms to the daily light–dark cycle, which ultimately is determined by the Earth's rotation. Exposure to certain environmental stimuli will cue a phase shift, and abrupt change in the timing of the rhythm. Entrainment helps organisms maintain an adaptive phase relationship with the ... It is the initial stage of dark reaction, during which atmospheric carbon dioxide enters plant cells. Then, an enzyme (rubisco) fixes the atmospheric CO2 and facilitates its binding to a (RuBP) ribulose-1, 5-bisphosphate (5-C compound).
