2. Pre-Requisites

Knowledge of Biochemistry, General Chemistry and Basic Mathematical Analysis. Teaching will be developed assuming that students have the optimal level of knowledge corresponding to the subjects of Fundamentals of Biochemistry, and Thermodynamics and Kinetics, corresponding to the first year of the degree.

3. Justification in the curriculum, relation to other subjects and to the profession

The subject is in the second year of the degree and aims to develop with greater intensity the knowledge of the functional or kinetic properties of enzymatic catalysis, acquired by students in the subjects Thermodynamics and Kinetics and Fundamentals of Biochemistry, of the first year of the Degree.

The contents of this subject are framed within the Degree in the second year, as a previous and essential training for the understanding and integration of knowledge that will be taught in subsequent courses of the degree, mainly within the subjects of Human Physiology and Metabolism and its Regulation in the third year of the Degree.

Likewise, the training received in the subject will be essential to achieve a professional competitive advantage, the mastery of enzymes as main elements or important tools, in preparative, degradative and synthetic analytical applications. This will enhance the performance of jobs in public and private companies, dedicated to health biotechnology (red), agri-food (green), industrial (white) and business management (gray), both in R+D and business management departments on knowledge, occupational risks, environment and quality.

According to art. 4 of the UCLM Student Evaluation Regulations, it must be provided to students who cannot regularly attend face-to-face training activities the passing of the subject, having the right (art. 12.2) to be globally graded, in 2 annual calls per subject , an ordinary and an extraordinary one (evaluating 100% of the competences).

Evaluation criteria for the final exam:
  • Continuous assessment:
    The modality assigned by default will assume the participation of the student in the Continuous Evaluation, unless he states otherwise (before the end of the class period) by means of an email to the teacher, provided that he has not completed 50% of the evaluable activities. A minimum grade of 4 will be required to add the grade obtained in the final exam with the rest of the activities. In case of not reaching the minimum grade (4/10) in the evaluation of the internship report, the report will be recoverable in the extraordinary call. The grades obtained in the preparation of the report of practices, problem solving and group work will be taken into account both in the ordinary and in the extraordinary call. The subject will only be considered passed if the set of all evaluable activities results in a grade of 5 or higher (out of 10).
  • Non-continuous evaluation:
    The modality assigned by default will assume the participation of the student in the Continuous Evaluation, unless he states otherwise (before the end of the class period) by means of an email to the teacher, provided that he has not completed 50% of the evaluable activities. A minimum grade of 4 will be required to add the grade obtained in the final exam (85%) with the grade of the practices (15%). In case of not reaching the minimum grade (4/10) in the evaluation of the internship report, the report will be recoverable in the extraordinary call. The grade obtained in the preparation of the practice report will be taken into account in both the ordinary and extraordinary call. The subject will only be considered passed if the set of all evaluable activities results in a grade of 5 or higher (out of 10).

Specifications for the resit/retake exam:
The grades obtained in the preparation of the report of practices, problem solving and group work will be taken into account both in the ordinary and in the extraordinary call. In case of not having reached in the ordinary call the minimum qualification in the laboratory practices, in the final test of the extraordinary call a series of questions will be included to evaluate if the student has acquired the competences related to these activities.
Specifications for the second resit / retake exam:
To pass this call there will only be a final test that will represent 100% of the grade, as long as the laboratory practices have been carried out and passed with a grade equal to or greater than 5.
