Does photosynthesis oxidize water
WebPhotosynthesis is a redox (oxidation-reduction) process. When water molecules are split apart, yielding O2, they are actually oxidized; that is, they lose electrons, along with H+ ions. CO2 is reduced to sugar as electrons and H+ ions are added to it. WebMay 1, 2024 · Photosynthesis is the process by which plants make energy from the use of chlorophyll and light. It is the process that oxidizes (removes electrons from) water to …
