I made some edits to photosynthesis and used another source.

Photosynthesis
Photosynthesis is a process by plants to convert sunlight into chemical energy that can be stored as carbohydrate molecules such as sugars to produce CO2 and water. The chemical equation of photosynthesis is an endergonic reaction since it absorbs the energy of sunlight to start the reaction. The photosynthesis equation is 6CO2 + 6H2O ——-> C6H12O6 + 6O2. Photosynthesis occurs when energy from light is absorbed in chloroplasts of plant leaves. In these reactions that depend on light (light-dependent reactions) some energy is used to take electrons from substances such as water to produce oxygen. The splitting of the water molecule frees the hydrogen to create NADPH (reduced form of NADP+) and ATP. In plants and algae, sugars are produced by a series of light-independent reactions called the Calvin Cycle. In the Calvin Cycle, carbon dioxide is included into already existing carbon compounds. Using the ATP and the NADPH produced in the light-dependent reactions, the compounds are reduced to form carbohydrates such as glucose. In the light-dependent reactions a molecule of the pigment chlorophyll absorbs a photon (particle of visible light with zero mass) and loses one electron. The electron is passed to pheophytin (modified chlorophyll) which passes the electron to a quinone (aromatic compound that is important as a coenzyme or electron acceptor and also used in making dyes) starting the flow of electrons down an electron transport chain that leads to a reduction of NADP to NADPH. This process creates a proton gradient across the chloroplast membrane which is used by ATP synthase to produce ATP. When a water molecule is split in a process called photolysis, the chlorophyll molecule gains the electron it lost and O2 is released. Light-dependent reactions occur in the thylakoid membrane (thylakoids are flattened sacs inside a chloroplast that carry out photosynthesis) and occur as cyclic and noncyclic. In the noncyclic reaction photons are captured in the light harvesting complexes (array of protein and chlorophyll molecules in the thylakoid membrane) of photosystem II (protein complexes that carry out the absorption of light and transfer of energy and electrons). The absorption of a photon from the light harvesting complex frees an electron that can be transferred to pheophytin (primary electron acceptor). While the electrons are traveling down the electron transport chain, protons (Hydrogen ions) are being pumped into the thylakoid space (chemiosmosis). An ATP synthase enzyme uses this to generate ATP during photophosphorylation and NADPH is also produced. The cyclic reaction only replenishes ATP without producing NADPH. In the light-independent reactions or the Calvin Cycle, the enzyme Rubisco (catalyzes the reaction that incorporates CO2 into the Calvin Cycle) captures carbon dioxide from the atmosphere and uses the NADPH (formed in the light-dependent reactions) to release three-carbon sugars that are later combined to form sugar and starch.
