Calvin cycle. The Calvin cycle (also known as Calvin-Benson cycle) is a series of biochemical reactions taking place in the chloroplasts of photosynthetic organisms. It was discovered by Melvin Calvin and Andy Benson at the University of California, Berkeley. It is one of the light-independent reactions and occurs in the stroma.
The Calvin cycle is called the dark cycle because it does not require light to proceed. Unlike light reactions, the Calvin cycle is a light-independent reaction, which means i â¦ t can and will occur in the dark as well as the light. 4 people found this useful.
