Light-independent reactions take place in plant chloroplasts. In this process sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.
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.
