Calvin cycle

n.
A series of chemical reactions that occur as part of photosynthesis, in which carbon is broken away from gaseous carbon dioxide and fixed as organic carbon in compounds that are ultimately converted into sugars.

[After Melvin Calvin.]

These bypass routes could support 60% higher biomass yield per turn of the Calvin Cycle and 30% higher yield per ATP.
In C3 plants, CO2 fixation and reduction via the Calvin cycle operates in the chloroplasts of mesophyll cells (MC), and the NADPH required for CO2 reduction also comes from MC.
It also lacks the Calvin cycle, which uses the carbon from carbon dioxide to build sugars, and it is unable to synthesize about half of the 20 essential amino acids.
The actual metabolic procedure, as shown in Figure 10-5, has been named the Calvin cycle.
The Calvin cycle, which has also come to be known as the C3 pathway because the first detectable product is a 3-carbon compound, is not the only means by which green plants fix carbon or incorporate it into sugars.

2] is converted into sugars like glucose is known as the Calvin cycle.
Most plants can get by with the simplest form of the Calvin cycle, in which a catalyst called RuBP combines with [CO.
An example is The Story of the Calvin Cycle, described here, in which students trace the biochemical steps of the Calvin cycle through a musical play.
