• Sommario/riassunto: Bioenergetics is the study of the way biological systems, usually at the molecular level, utilize and convert energy in order to drive the biochemical reactions that constitute life. However, because of its often quantitative basis and the amount of technical jargon, the subject tends to alienate and intimidate students. This beautifully illustrated text has a lucid and logical approach to the subject. The text uses the modern perspective throughout so that the student is given an easily assimilable, logical introduction to the important concepts of the subject, particulary the core concept, the 'chemiosmotic theory'. It has been specifically designed to make information easily accessible by devoting each double-page spread to one topic. Within the spread, a variety of carefully constructed diagrams present information in a concise and innovative manner. The text is further enhanced by a comprehensive guide to additional reading. Original, easily understood combination of visual and written information. 43 double-page speads give a clear and concise introduction to this traditionally difficult subject. The most up to date text available, covering all modern molecular genetic techniques. Competitively priced.
