What is the Calvin cycle?

Answer 1

The Calvin cycle is the dark reaction in plants, that results in formation of the glucose molecule.

The Calvin Cycle synthesizes G3P

Basically, Photosynthesis is divided up into the Light reactions and the Calvin Cycle. The "photo" part is the light reaction part, and the "synthesis" is the Calvin Cycle.

The Calvin Cycle's whole existence is to produce sugar. It does this with incorporating CO2 to eventually produce G3P, a sugar that can go on to make glucose etc... The Calvin cycle is powered by NADPH and ATP, which come from the light reactions. Of course this is a simplified version, as there are a number of intermediate molecules, but the idea is the same.For more info I would recommend reading Campbell and Reece (6th ed, 2005)

Answer 2

The Calvin cycle is a series of chemical reactions that take place in the chloroplasts of plants during photosynthesis. It converts carbon dioxide from the atmosphere into glucose, a form of sugar that the plant can use for energy. The cycle involves several steps, including carbon fixation, reduction, and regeneration of RuBP.
