Book

Photosynthesis: Principles, Mechanisms and Clean Energy Applications presents a comprehensive examination of photosynthesis from fundamental biological principles to its emerging role in clean-energy systems. The book explains how plants, algae, cyanobacteria and photosynthetic bacteria capture solar radiation and convert it into chemically stored energy.

Beginning with the basic chemistry and organization of photosynthesis, the book covers chloroplast structure, photosynthetic pigments, photon energy, light-harvesting complexes, Photosystems I and II, electron transport, the Z-scheme, proton-motive force and ATP synthesis. It then examines carbon fixation through the Calvin-Benson cycle and explains C3, C4 and CAM pathways, photorespiration, stomatal gas exchange and the environmental factors controlling photosynthetic performance.major focus is the connection between photosynthesis and sustainable energy. The book discusses photosynthetic efficiency, quantum yield, photon-energy requirements, thermodynamics, biomass production, algae, photobioreactors, biofuels, hydrogen production, artificial photosynthesis, bioelectrochemical energy conversion and carbon capture. It also examines practical limitations including light attenuation, water availability, temperature, oxygen inhibition, harvesting requirements and energy-return considerations.

The final sections explore strategies for improving photosynthetic efficiency, including enhanced light harvesting, RuBisCO engineering, reduced photorespiration, carbon-concentrating mechanisms, photoprotection, stomatal engineering, genetic engineering and synthetic biology.
