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.
