Dark cycle biology
WebThe decomposition of macroalgal detritus (tubular and planar Ulva spp.) was studied in a microcosm under a daily light:dark cycle to simulate the decomposition on intertidal sediment. The consequences of bloom decay were evaluated in the bulk water phase and in the sediment. Inorganic nutrients (NO3 - , NO2 - , NH4 + , PO4 3- and SiO3 2- ), … WebMark the period of darkness for the light/dark cycle with a black rectangle under the x-axis.

In the Calvin cycle, the ATP and NADPH formed during light reaction drive the reaction and convert 6 …
WebAug 19, 2013 · Abstract. The electric light is one of the most important human inventions. Sleep and other daily rhythms in physiology and behavior, however, evolved in the natural light-dark cycle [1], and electrical lighting is thought to have disrupted these rhythms. Yet how much the age of electrical lighting has altered the human circadian clock is unknown.
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). Thus, the association of carbon dioxide and ribulose-1, 5-bisphosphate, … See more It is the second and the most crucial stage of the Calvin cycle, which uses energy molecules (ATP and NADPH) coming from the light-dependent photosynthetic phase and the specific enzyme system.
