where in the plant cell does the calvin cycle take place?
in the stroma of chloroplast
these reactions are closely coupled to the thylakoid electron transport chain as the energy required to reduce the carbon dioxide is provided by nadph produced in photosystem i during the light dependent reactions. the process of photorespiration, also known as c2 cycle, is also coupled to the calvin cycle, as it results from an alternative reaction of the rubisco enzyme, and its final byproduct is another glyceraldehyde-3-p.

the calvin cycle, calvin–benson–bassham (cbb) cycle, reductive pentose phosphate cycle or c3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms.

the immediate products of one turn of the calvin cycle are 2 glyceraldehyde-3-phosphate (g3p) molecules, 3 adp, and 2 nadp. (adp and nadp are not really "products." they are regenerated and later used again in the light-dependent reactions). each g3p molecule is composed of 3 carbons. for the calvin cycle to continue, rubp (ribulose 1,5-bisphosphate) must be regenerated. so, 5 out of 6 carbons from the 2 g3p molecules are used for this purpose. therefore, there is only 1 net carbon produced to play with for each turn. to create 1 surplus g3p requires 3 carbons, and therefore 3 turns of the calvin cycle. to make one glucose molecule (which can be created from 2 g3p molecules) would require 6 turns of the calvin cycle. surplus g3p can also be used to form other carbohydrates such as starch, sucrose, and cellulose, depending on what the plant needs.
