What are the steps in photosynthesis?

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

Step 1-Light Dependent:CO2 and H2O enter the leaf

Step 2- Light Dependent: Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2

Step 3- Light Dependent: The electrons move down to enzymes

Step 4-Light Dependent: Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
Step 5-Light independent: 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.

Step 6-Light independent: The calvin cycle converts 3CO2 molecules from the atmosphere to glucose
