Answer: Calvin cycle
Explanation: Calvin cycle is a cyclic pathway in which carbon dioxide is assimilated. The process of photosynthesis is divided into two: The light reactions and carbon fixation reactions. In light reactions, chlorophyll and other light absorbing pigments absorb light from the sun and conserve it as ATP and NADPH. In carbon fixation reactions, carbon dioxide reduced to sugars in a cyclic pathway driven by ATP and NADPH. This pathway is known as the Calvin cycle.
