Photosynthesis is the set of light-driven biochemical processes by which phototrophic organisms convert electromagnetic energy into chemical energy, primarily storing it in carbohydrates synthesized from inorganic carbon. In oxygenic photosynthesis, chlorophyll-based reaction centers (photosystems I and II) located in thylakoid membranes couple photon absorption to charge separation, driving linear electron transport from water to NADP⁺, generating O₂, NADPH, and a proton motive force used for ATP synthesis via photophosphorylation. The resulting ATP and NADPH fuel the Calvin–Benson–Bassham cycle, which fixes CO₂ into organic molecules, integrating tightly regulated metabolic, redox, and signaling networks that respond to cellular and environmental conditions.
Plants use photosynthesis to harvest energy from sunlight. Now researchers at the Technical University of Munich (TUM) have applied this principle as the basis for developing new sustainable processes which in the future ...

Chemistry is increasingly making use of the trick plants can do with photosynthesis: driving chemical reactions that run poorly or do not occur spontaneously at all with light energy. This requires suitable photocatalysts ...
