Steps Of Photosynthesis

CO2 and H2O enter the leaf

Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2

The electrons move down to enzymes

Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
