The Photosynthetic Membrane

Mehr zum Buch

The proteins that gather light for plant photosynthesis are embedded within cell membranes in a site called the thylakoid membrane. These proteins form the light harvesting antenna that energizes vital photosynthetic processes, including water oxidation, oxygen evolution, and ATP synthesis by ATP synthase, which utilizes the generated proton gradient. This work serves as an introduction to the design and function of the light harvesting photosynthetic membrane, a crucial structure of life. It explores the membrane's underlying structure, the variety and roles of its proteins, the atomic structures of light harvesting complexes, and the molecular mechanisms of light harvesting and energy transformations. Additionally, it discusses the adaptations to different light environments. Through the example of the photosynthetic membrane, the text illustrates how complex biological structures employ principles of chemistry and physics to perform biological functions. This resource will attract a broad audience, including undergraduate and postgraduate students, as well as researchers in biochemistry, molecular biology, biophysics, plant science, and bioengineering.
