Calvin Cycle
Calvin cycle
A chloroplast-stroma cycle that uses ATP and NADPH to incorporate carbon dioxide into triose phosphate and regenerate its carbon acceptor.
Overview
EXPLORE BY LEVELThe Chloroplast reactions that use ATP and NADPH to incorporate carbon dioxide into carbohydrate precursors while regenerating RuBP. uses ATP and An electron-carrying molecule that supplies reducing power for biosynthesis and cell protection. made by the light reactions. It adds carbon from CO₂ to a small carbon molecule and makes A three-carbon sugar phosphate; after three carbon-fixation turns, one G3P is the net product that can leave the Calvin cycle., which can be used to build sugars and other molecules.

Calvin–Benson-cycle flux depends on RuBisCO activation, ATP/NADPH supply, inorganic phosphate exchange, metabolite pools, and light-responsive regulation. The cycle does not directly output one glucose molecule per turn.
