Reihe: At a Glance

Bioenergetics is the study of the way biological systems, usuallyat the molecular level, utilize and convert energy in order todrive the biochemical reactions that constitute life. However,because of its often quantitative basis and the amount of technicaljargon, the subject tends to alienate and intimidate students. Thisbeautifully illustrated text has a lucid and logical approach tothe subject. The text uses the modern perspective throughout sothat the student is given an easily assimilable, logicalintroduction to the important concepts of the subject, particularythe core concept, the 'chemiosmotic theory'. It has beenspecifically designed to make information easily accessible bydevoting each double-page spread to one topic. Within the spread, avariety of carefully constructed diagrams present information in aconcise and innovative manner. The text is further enhanced by acomprehensive guide to additional reading.
* * Original, easily understood combination of visual and writteninformation.
* 43 double-page speads give a clear and concise introduction tothis traditionally difficult subject.
* The most up to date text available, covering all modernmolecular genetic techniques.
* Competitively priced.
