____________ are required for the formation of one molecule of glucose during the Calvin pathway.
____________ are required for the formation of one molecule of glucose during the Calvin pathway.
Open in App
Solution
The correct option is C 6CO2+18ATP+12NADPH
ATP and NADPH are assimilatory powers formed during light reaction of photosynthesis. These are utilised to synthesise glucose. The synthesis of glucose occurs in the stroma of chloroplast and is independent of light. The detailed pathway of synthesis of glucose was studied by Calvin and his co-workers. This biosynthetic pathway is called Calvin cycle. The Calvin cycle includes three stages - carboxylation, reduction and regeneration.
Carboxylation does not require ATP and NADPH. ATP and NADPH are required during the reduction and regeneration stage of the cycle.
For the synthesis of one molecule of glucose, 6CO2, 18 ATP and 12 NADPH are required.
12 ATP and 12 NADPH are utilised during the reduction stage of the Calvin cycle.
6 ATP are required during the regeneration stage.
