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, t
