This third volume of Short Reports from the International Council of Scientific Unions comprises the proceedings of the conference on bioenergetics held at Hannover in September 1984. The reports are divided into two sections. Those in the first section come from the symposia and colloquia lectures and are grouped under ten topics in microbial bioenergetics and the relation between protein structure and function. Those in the second section come from the poster sessions, covering a further ten topics ranging from electron transport and proton motive forces to metabolic regulation and energy transducing membrane components. The format of the short report makes it possible to present a great deal of information in compact and easily accessible form, which can be followed up in greater depth using the bibliographies included in each report. The comprehensiveness and convenience of this book makes it most useful to researchers interested in historical developments across the range of bioenergetics, as well as those in related fields such as biochemistry and biophysics.
