The series, Molecular and Cell Biochemistry, covers the whole of modem biochemistry, integrating animal, plant and microbial topics.

The books in this series are designed for junior undergraduates and diploma students in all biological sciences. They cover the field of modern biochemistry, integrating animal, plant and microbial topics. Each chapter is prefaced by a list of learning objectives, with short summaries, revision aids and end-of-chapter questions. This volume deals with the generation of biologically usable energy in living systems.
