Description

Comprehensive Biochemisty, Volume 22: Bioenergetics focuses on comprehensive biochemistry that provides a chemical approach to the understanding of the phenomena of life.

This book is devoted to certain aspects of organic and physical chemistry, aspects considered pertinent to the interpretation of biochemical techniques, and chemistry of biological compounds and mechanisms. The topics discussed include the methods and scope of quantum biochemistry, long range dipole-dipole transfer, and characteristics of the charge-transfer absorption band. The dye-sensitized photoconductivity, facilitation of solute diffusion by catalytic carriers, and coupling of primary and secondary translocation are also covered in this publication.

This volume is valuable to biochemists and researchers concerned with biogenetics.
