Methodologies
Methodologies Description
Mixed objective/subjective test Trial combining different types of questions to assess the knowledge acquired in the various activities undertaken.
Problem solving With the resolution of practical problems and work with molecular models will delve into the practical application of the concepts explained in the lectures and will take advantage of the smaller size of the group to generate questions to help reflection and personal involvement of students in the process of learning.
Guest lecture / keynote speech
Oral presentation complemented by the use of audiovisual media about chemical biological processes in order to build the capacity of understanding of the issues by the students.
Diagramming Diagrams of the metabolic routes
Laboratory practice The students will work in the lab experimentally setting up various techniques related to the subject of the isolation, characterization and identification of biomolecules. They will learn to work in the laboratory in accordance with safe and reproducible patterns. They also will learn how to present and interpret the results and discuss them according to knowledge acquired in the theoretical part of the subject by preparing a lab report.

Assessment comments
-The performance of practices is mandatory to pass the course  and qualification rate in the final grade

1.-Continuous assessment: assessment is continuously being valued. To pass the course in continuous assessment in June you need to have at least 4O% of the total mark in the first part (Tracks 1-4) and the practices. In  July option concurs with all matter.

Final Evaluation. In the July / June may make an assessment at term (not taken into account the marks obtained during the course): it consist on a  theoretical and a practicall exam in the laboratory, to be prepared on your own. The teacher shall be notified of this option before May 10 for evaluations (June or July).

-Following the recomendations of  the Faculty of Sciences Commitee, Distinction will be awarded among those students who obtain the highest marks (marks) in the first assessment option (June) .

Other comments
It is essential to participate in classes and activities as well as work every day with the support of the recommended bibliography taht will help to better understanding and comprehension of the subject study. Continued assistance is recommended since there will be classes for solving exercises and scoring experimental problems will help the study and preparation of the final examination by the student. Also attending tutorials to resolve questions and issues on the agenda that are of particular difficulty for the student is advised.
