Objectives
Objectives
The course of Redox Biochemistry and Bioelectrochemistry has as objectives that students know the fundamental concepts of redox biochemistry, namely reduction and oxidation reactions, electron transfer, concepts of oxidants and reducers, free radicals and oxidative stress, spontaneity of reactions, signaling and redox regulation and electrocatalysis. Students will also learn the theoretical and practical concepts necessary for the concrete study of biochemical redox phenomena through bioelectrochemical techniques. Recognize the most suitable techniques for practical application depending on the system or objective under study and develop skills in the area for current and emerging applications.

Teaching methodologies and assessment
Teaching methodologies and assessment
Theoretical classes (T) are face-to-face, privileging direct contact with students. Interactive lectures and Problem-Based Learning classes are planned. In practical classes (PL) students will contact with some examples of experimental techniques, analyze results and apply the knowledge acquired in the theoretical classes. Case studies will also be carried out.
