Photosynthesis takes place in the leaves of a plant. Carbon Dioxide, water, and Oxygen can enter and exit through the pores called Stomata. The Clorophyll in the Chloroplasts inside the leaf's cells absorbs light. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
Sunlight hits the second pigment molecule, which allows the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
the calvin cycle is The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate. The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into glucose. It takes 6 rotations to make 1 glucose
