Calvin Cycle - Calvin Cycle
The reduced pentose phosphate cycle, also known as the Calvin-Benson cycle, is the carbon dioxide fixation cycle that corresponds to the light reaction of photosynthesis. It consists of the following three steps. 1. Three molecules of CO 2 react with three molecules of ribulose-1.5-bisphosphate (RuBP) to produce six molecules of 3-phosphoglycerate. 2. This is reduced by six molecules of ATP and NADPH to produce six molecules of glyceraldehyde-3-phosphate (GAP). 3. Three molecules of ribulose-5-phosphate are produced from five molecules of GAP, and RuBP is regenerated in the process. Sucrose is produced from some of the GAP produced in the reduction step, and three molecules of ATP and two molecules of NADPH are required to convert one molecule of CO 2 into carbohydrate. This cycle is localized in the stroma of chloroplasts.

還元型ペントースリン酸回路,カルビン=ベンソン回路とも,光合成の明反応に相当する炭酸固定回路。次の3段階よりなる。1.3分子のCO2が3分子のリブロース-1.5-二リン酸(RuBP)と反応して6分子の3-ホスホグリセリン酸ができる。2.これが6分子のATPおよびNADPHによって還元されて6分子のグリセルアルデヒド-3-リン酸(GAP)になる。3.GAP5分子からリブロース-5-リン酸3分子がつくられ,その過程でRuBPが再生される。還元段階で生じるGAPの一部からショ糖が作られ,CO21分子が炭水化物になるのにATP3分子とNADPH2分子が必要。この回路は葉緑体のストロマに局在する。
