In plants, algae and cyanobacteria, photosynthesis releases oxygen. This is called oxygenic photosynthesis. Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms.
Oxygenic photosynthesis refers to the photosynthesis that occurs in plants, algae, and cyanobacteria in which the final electron acceptor is water. It occurs in two steps: light reaction and dark reaction. The light-trapping pigments used in oxygenic photosynthesis are chlorophyll A and B.
Abstract. Cyanobacteria and plants carry out oxygenic photosynthesis. They use water to generate the atmospheric oxygen we breathe and carbon dioxide to produce the biomass serving as food, feed, fibre and fuel.
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.
The origin of oxygenic photosynthesis was the most important metabolic innovation in Earth history. It allowed life to generate energy and reducing power directly from sunlight and water, freeing it from the limited resources of geochemically derived reductants.
In the oxygenic, that is molecular oxygen (O 2) generating (non-cyclic) photosynthesis reaction system, high energy (excited) electrons are passed from the reaction center to a set of membrane proteins known as the electron transport chain (“etc”).
Oxygenic photosynthesis begins with light absorption, followed by excitation energy transfer to the reaction centres, primary photochemistry, electron and proton transport, NADPH and ATP synthesis, and then CO 2 fixation (Calvin–Benson cycle, as well as Hatch–Slack cycle).
Oxygenic photosynthesis — the conversion of sunlight into chemical energy by plants, green algae and cyanobacteria — underpins the survival of virtually all higher life forms.
Oxygenic photosynthesis is the process in which oxygen and carbohydrates are produced from water and carbon dioxide utilizing sunlight. With the ability of converting solar energy into chemical energy, oxygenic photosynthesis remains one of the most important...
