Bioenergetics of Photosynthesis covers the transformation of energy in biological systems, with an emphasis on photosynthesis. The biochemical and biophysical aspects are given much focus in this book. The historical development of the concepts used in this book is reviewed. This reference also analyzes experimental data and their results. This publication contains 12 chapters. The first chapter introduces the concept of photosynthesis. Then, the next chapter explores the relationship between chloroplast structure and function . Other concepts covered in this book include the primary events (energy transfer and light absorption), delayed light emission, and chlorophyll fluorescence. The mechanism of excitation energy, oxygen evolution, and chlorophyll fluorescence are also explained. Furthermore, this book discusses the electron transport pathway, primary acts of energy conservation in chloroplast membranes, and molecular organization of chlorophyll. Finally, it describes the relationship of the structure of chloroplast membrane to energy coupling and ion transport. This book will be a good resource for students and researchers alike, especially in the fields of cell biology, plant physiology, biochemistry, and biophysics.
