Expert Answer:

The Calvin-Benson cycle is a series of biochemical reactions that takes place in the stroma of chloroplasts in photosynthetic organisms. It was discovered by Melvin Calvin, James Bassham and Andrew Benson at the University of California, Berkeley . It is one of the light-independent reactions or dark reactions.

The Calvin Benson cycle goes in (you guessed it) cycles. For every one complete turn of the cycle fixes one CO2 molecule and regenerates an RuBP molecule. Calvin Benson cycle consists of three subsequencing stages: CO2 fixation, CO2 reduction, and regeneration of ribulose bisphosphate (RuBP). In this process, carbon dioxide is reduced to carbohydrates. This reaction utilises ATP and NADPH2.
