    To form one molecule of glyceraldehydes phosphate In Calvin cycle :

    A)  9ATP and 36 NADPH are required

    B)  6 ATP and 6 NADPH are required

    C)  3 ATP and 3 NADPH are required

    D)  9 ATP and 6 NADPH are required

    Correct Answer: D

    Solution :

                    Three molecules of \[{{O}_{2}}\]must be fixed to generate one molecule of glyceraldehydes 3-phosphate (three carbon molecules), three ATP and two NADPH are required for each \[C{{O}_{2}}\] to be converted to glyceraldehydes 3-phosphate. \[3C{{O}_{2}}+6NADPH+9ATP\xrightarrow[{}]{{}}\] Glyceraldehyde 3-phosphate   \[+\text{ }6NAD{{P}^{+}}+9ADP+8Pi\]
