Calvin cycle

[′kal·vən ‚sī·kəl]
(cell and molecular biology)
A metabolic process during photosynthesis that uses light indirectly to convert carbon dioxide to sugar in the stroma of chloroplasts. Also known as Calvin-Benson cycle; carbon fixation cycle.

The process has come to be known as the C3 pathway or the Calvin cycle.
Then this carbon is fixed just as it is in the normal Calvin cycle metabolism.
Instead of partitioning metabolites in space (between mesophyll and bundle sheath cells), CAM plants use PEP carboxylase to fix the carbon into malate, which is then stored until the next day, when the carbon is released and refixed in normal Calvin cycle metabolism.
2] at night, fix it into malate, the then refix it into Calvin cycle sugars the next day.
The intermediary molecule formed by these plants in the Calvin cycle is a four-carbon compound, so these are known as C4 plants.
In my classroom, the details of the Calvin cycle (formally the Calvin-Benson-Basham cycle) are presented after a general discussion of the big picture of photosynthesis in the global ecology of the planet.

Due to my general enthusiasm for biology, and all of the other biological plays and activities I employ in teaching, my students are used to and expect active participation in learning a complicated process such as the biochemistry of the Calvin cycle.
