Question

explain briefly about dark reaction

Answer 1

Dark Reaction is the second step in the mechanism of photosynthesis. The chemical processes of photosynthesis occurring independent of light is called dark reaction. It takes place in the stroma of the chloroplast. The Dark reaction of photosynthesis is purely enzymatic and it is slower than the light reaction. In dark reactions, two types of cyclic reaction occur. They are Calvin cycle or C3 Cycle and Hatch Slack Cycle or C4 cycle.

Dark reaction

The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma. It involvesC3 and C4 cycle.
