      Six turns of Calvin cycle are required to generate one mote of glucose. Explain.


                      Ribulose 5 phosphate is a five carbon compound which accepts atmospheric  in presence of RuBisCo and form 2 molecules of 3PGA,  carbon compound. It uses 3 ATP and 2 NADPH to fix one molecule of  per cycle of Calvin. So, to fix 6 molecules to form 6 carbon compound glucose 6 cycles are required as mentioned below.
    In Out
    18 ATP 12 NADPH One glucose molecule 12 NADP
