The course on Bioenergetics will focus on the various aspects of energy transduction performed by living organisms. By the end of the course the student should understand the thermodynamic and kinetic principles involved in energy transduction and be able to solve numerical application problems. He should know the components and organisation of the respiratory chains and photosystems and understand the mechanisms of electron/proton coupling. He should be aware of the diversity of bacterial respiration and photosynthesis. It is also expected that the student develops skills in searching, understanding, and discussing the scientific literature in this field.

The course is organized in lectures and workshops.
The lectures will cover the topics of the program.
The workshops will be dedicated to numerical applications in Bioenergetics and to the presentation and discussion of frontline scientific articles by the students.
The final evaluation is the result of a theoretical examination paper (60%), and presentation and discussion of scientific articles (40%).
To be approved in this curricular unit, the grade of the theoretical examination paper cannot be smaller than 8.5/20.
