Photosynthesis Process Template

Steps of Photosynthesis Process:

• 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.

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

Why Photosynthesis is important?

• It is the number one source of oxygen in the atmosphere.
• It contributes to the carbon cycle between the earth, the oceans, plants and animals.
• It contributes to the symbiotic relationship between plants, humans and animals.
• It directly or indirectly affects most life on Earth.
• It serves as the primary energy process for most trees and plants.
