In non-cyclic photophosphorylation 1 ATP and 2 $NADPH_2$ molecules are produced.
In cyclic photophosphorylation 2 ATP molecules are produced.
For production of one molecule of Glucose 18 ATP and 12 $NADPH_2$ molecules are reqiured.
According to my understanding,6 turns of cyclic and non-cyclic photophosphorylation is required to produce one molecule of glucose.
Because 6 turns of non cyclic photophosphorylation will produce 12 $NADPH_2$ and 6 ATP molecules.
And cyclic photophosphorylation will produce 12 ATP molecules.
Total=12 $NADPH_2$ and 18 ATP.
I think Iam missing something , Please answer me if I am correct or not.
