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 new UC Riverside-led study reveals how common small particles produced by nature as well as human activities can transform upon entering plant cells and weaken plants' ability to turn sunlight into food. The discovery offers ...
