Learning outcomes
At the end of the course the student will know the main metabolic processes in humans and the general mechanisms of metabolic regulation. Furthermore, the student will understand exercise energetics and the molecular mechanisms of adaptions to training responsible of performance enhancement and associated to the beneficial effect of exercise on human health.

Teaching methods
Traditional lectures (24 hours)
Assessment methods
The learning assessment is conducted through a final examination at the end of lessons. The exam consist of a witten test (multiple choice questions) plus a few general questions. The course unit of Metabolic Biochemistry is part of the integrated course of "Human Biochemistry and Nutrition" (together with other units "Biochemistry" and "Human Nutrition). The final vote of the integrated course results from the mean of the scores obtained in the three course units.
