In this transfer, the CO2 is “reduced,” or receives electrons, and the water becomes “oxidized,” or loses electrons. Photosynthesis in green plants is comprised of the _, in which H20 is oxidized, and _, in which CO2 is reduced Select an answer and submit. Thus, the purpose of water in photosynthesis is to supply the electrons for the reduction of carbon dioxide to a carbohydrate. Light reactions (photo) 2. As a sink of carbon dioxide (CO2) peat bogs slow anthropogenic climate change, but warming climate increases the likelihood of drought which may reduce net ecosystem exchange (NEE) and increase soil respiration, tipping C sinks to sources.

In photosynthesis, the carbon in CO2 is _____ to form glucose. In chemical terms, oxidation refers to a chemical process whereby an atom or molecule loses an electron. Chemical reactions involve the shifting around of electrons from one place to another, so a reduction of one component is accompanied by the oxidation of another. Photosynthesis involves oxidation and reduction by oxidizing the oxygen in water and reducing the carbon in carbon dioxide. Photosynthesis, derived from the Greek words photo, meaning "light," and synthesis "putting together," is a process used by plants and some bacteria to harness the energy from sunlight to convert water and carbon dioxide to produce sugar (glucose) and oxygen. Photosynthesis is the process used by plants and a few microorganisms to transform sunlight, carbon dioxide and water into two products; carbohydrates that they use to store energy, and oxygen that they release into the environment.
