It might help you to understand all of this if we look at what goes in and what comes out of the Calvin cycle in tabular form. To make a molecule of glucose requires 6 turns of the cycle . So, it requires approximately the equivalent of 54 ATPs to make a molecule of glucose. The final drawing represents a summary of the entire process of photosynthesis. Notice that light and water go into the noncyclic photophosphorylation wheel.
Light provides the power to turn the wheel.
As the wheel turns it pushes the two smaller wheels. Carbon dioxide enters and G3P comes out. The ADP and NADP from the Calvin cycle return to the light dependent reactions. Now for some sophisticated movies about photosynthesis go to the following website and investigate the plant cell there. The movies are a bit slow, but you can open up another window of your browser and do other stuff while it is loading.
