Electron Transfer and Energy Transduction in Photosynthesis: An Overview

Part of the Advances in Photosynthesis and Respiration book series (AIPH, volume 4)


The intent of this book is to provide readers with a comprehensive view of the activities, structure, and molecular biology of the components of the photosynthetic apparatus in chloroplast thylakoid membranes. The sections that follow provide coverage of major topics that represent foci of active research investigations. In this introductory chapter we provide a brief overview of thylakoid properties and a guide to our readers to appropriate chapters in the following sections of this book, where our colleagues have provided in-depth coverage of the topics outlined in this overview chapter. We outline the activities of the two photoreactions (Photosystems I and II) and discuss the electron carriers that mediate transfer of electrons between these light-driven enzyme systems. Thylakoid energy transduction is described in terms of the origins of the protonmotive force and its subsequent utilization by the chloroplast ATP synthase, CF1 Finally, we provide some comments on the molecular biology and evolution of the eukaryotic photosynthetic apparatus.
