Free Energy Transduction in Biology

Free Energy Transduction in Biology: The Steady-State Kinetic and Thermodynamic Formalism focuses on the steady-state kinetic and thermodynamic formalism related to free energy transduction. As the word ""formalism"" implies, the discussion concerns general principles and methods and not details of proposed mechanisms in the various special cases.
Organized into seven chapters, this book first describes the diagram method, which is the main analytical tool in the study of discrete state, cycling system. The next chapter describes the essential topic of cycles and cycle fluxes. Some chapters discuss the more important bioenergetic principles that emerge from the diagram approach. This book is also concerned with somewhat more specialized aspects of the subject (stochastics and fluctuations) and interacting subsystems and multienzyme complexes, including oxidative phosphorylation.
