Objectives
At the end of the semester the student should readily:
Describe the constitution and structure of proteins. Distinguish globular from fibrous proteins. Know several examples of protein structure-function correlation, including the mechanism of some enzimatic reactions. Know experimental methods for isolating and characterizing proteins. Understand the main concepts on enzyme catalysis and regulation. Interpret enzyme kinetic data and calculate kinetic parameters according to the Michaelis-Menten model. Carry out simple enzyme assays.
Name and describe the constitution, the structure and the function of common carbohydrates.
Name and describe the constitution and strucures of DNA and RNA. Describe the functioning and the regulation of the replication, transcription and translation steps. Know the basic procedures of recombinant DNA techniques.
Describe the constitution, structure and properties of biological membranes and the characteristics of the fluid mosaic model. Know the molecular systems associated to biological transport.
Understand the central role of the pair ATP/ADP and of other nucleotides in metabolism. Be familiar with the basic concepts of bioenergetics. Perform quantitative calculations in bioenergetics. Describe the main metabolic pathways in the cell and their regulation, with emphasis on the central metabolic pathway and on photosynthesis. Understand the difference between substrate-level phosphorylation and phosphorylation linked to electron-transfer processes.
Be competent using materials and equipments commonly found in a biochemical lab, as well as acquiring, treating, presenting and discussing experimental results.

Teaching method
The course is organized in lectures, laboratory classes and workshops. The students must apply the concepts developed in the lectures to the analysis of the experimental results obtained in the laboratory and to problem solving in the workshops.
Evaluation method
Evaluation
The final evaluation is the result of a theoretical examination paper (75%) and a practical component (25%) that accounts for the laboratory work. The attendance to the laboratory classes is compulsory besides 70% of lectures (T and TP).
