The light-independent reactions of photosynthesis, also known as the Calvin cycle, use and produce a variety of molecules. Sort

Margaret [11]

Molecules brought in and used in the calvin cycle - Carbon dioxide $(CO_2)$ , Ribulose bisphosphate (RuBP)

Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+

Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH

Explanation:

Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:

1. Carbon fixation - $(CO_2)$ combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).

2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).

3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.
