Photosynthesis By Rose Gabriel

Photosynthesis Formula: The formula is 6CO2 + 6H20 ---> C6H12O6 + 6O2 in other words it is Carbon Dioxide + Water ---> Glucose + Oxygen. Also the type of reaction photosynthesis is anabolic because it is making something small to something bigger.

Major Steps of the Light Reaction: The major steps of the light reaction is, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron molecules like ATP and NADPH. Light energy is produced in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts. In light reactions (the Calvin cycle), carbohydrate molecules are gathered together from carbon dioxide using the chemical energy produced during the light reactions.

Major Steps of the Calvin Cycle: The Calvin cycle has three stages. In stage 1, the enzyme RuBisCO takes in carbon dioxide into an organic molecule, 3-PGA. In stage 2, the organic molecule is made smaller by using electrons given by NADPH. In stage 3, RuBP, the molecule that starts the cycle, is made again so that the cycle can continue on.

Perspective: Photosynthesis is a chemical process where plants and algae that contain chlorophyll capture energy from the sun, and use carbon dioxide and water from the environment to then make the sunlight to food (glucose), while at the same time creating oxygen and water as products.
