Answer: It is the carbon dioxide assimilation or carbon fixation reactions or the Calvin cycle.
Explanation: Carbon dioxide assimilation reactions are light independent reactions of photosynthesis. They do not require light to occur, thus they occur in the dark. The carbon dioxide assimilation reactions are driven by ATP and NADPH that are produced in the light dependent reactions of photosynthesis. The carbon dioxide assimilation reactions are the second stage of photosynthesis. It involves the incorporation of three molecules of carbon dioxide into three molecules of ribulose 1,5-bisphosphate in a cyclic pathway known as the Calvin cycle. In these reactions, triose phosphates are produced which serve as precursors for synthesis of glucose and other related substances such as starch.
