Learning objectives

At the end of the training activity, the student is expected to have acquired the fundamental knowledge of basic biochemistry and demonstrate that he is able to apply it in minimally complex contexts such as the nutrition / fasting cycle. In particular, the student must be able to:
1) describe the function of the main biological macromolecules and the mechanism of action of enzymes (KNOWLEDGE AND UNDERSTANDING)
2) describe how carbohydrates, lipids and proteins are degraded and synthesized (KNOWLEDGE AND UNDERSTANDING)
3) apply the knowledge of biochemistry and metabolism to the understanding of the chemical processes involved in the extraction of energy from nutrients (ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING)
4) apply the knowledge of biochemistry and metabolism to the understanding of the processes underlying the obtaining of food from animal and plant sources (ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING)
5) expose in an organic way and with a language that makes use of the appropriate scientific terminology the main metabolic pathways and their integration (COMMUNICATION SKILLS AND LEARNING SKILLS)

Prerequisites

To deal with the topics of the Biochemistry course, students should possess a basic knowledge of Chemistry and Organic Chemistry.

Teaching methods

The oral lessons will focus on fundamentals of biochemistry with the support of slides (available weekly to the students on Elly website). The main metabolic processes will be discussed with the help of concept maps to help students focus on the relationships among metabolic pathways and their intermediates. A number of lessons will focus on the discussion of case studies and current topics, in order to stimulate the application of biochemistry to food, nutrition, gastronomy and the use of GMO in the agri-food sector.

Assessment methods and criteria

The exam for the Biochemistry course includes a written test consisting of two parts: a part with closed answers and a part with open answers. The part with closed answers will consist of 16 multiple choice quizzes (of which 2 on the monographic parts), each with a maximum score of 1. The part with open answers will consist of two questions on the topics covered in the course that will give a maximum score of 7 each. The rating scale is 0-30 cum laude. The laude is given to those who reach 30 as a final score and demonstrate in the open questions part deep knowlegde and understanding of the subject and extreme clarity. During the exam, it will not be possible to use any kind of material (dictionaries, glossaries, manuals, element tables, calculators). If even only one of the two open questions that give 7 points will be evaluated with a mark of zero points, the test will be considered insufficient.
The mark of the written test is communicated within ten days following the test. Students will have 7 days after the publication of the results to refuse the vote on Esse3 platform. Students with DSA / BES must first contact Le Eli-che: support for students with disabilities, D.S.A., B.E.S. (http://cai.unipr.it).
