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.
A genetic master map of ancient grasses could be the key to future-proofing global food supplies, according to a new study revealing why some crops are naturally better at surviving climate change than others.
