Educational objectives
The course aims to provide students with in-depth knowledge of:
– protein structure and function;
– vitamins and coenzymes;
– biological membranes;
– principles of bioenergetics.
Upon completion of the course, students will be able to critically describe the structure–function relationships of proteins and the molecular mechanisms underlying enzymatic catalysis, as well as the processes of transport across biological membranes and the main mechanisms of biosignaling. In addition, students will acquire the ability to interpret metabolic processes in accordance with the principles of thermodynamics, with particular emphasis on the mechanisms of chemical energy conservation and transformation.
Prerequisites
To successfully follow the Biochemistry course, it is necessary to have acquired basic knowledge of Chemistry and introductory Biochemistry, as well as Biology, as outlined in the syllabus of the semester filtro.
Teaching methods
The course is organized as follows:
Lectures covering all topics of the syllabus. During the lectures, students are encouraged to participate and ask for clarification.
Scheduled meetings, held in the classroom or via the Teams platform, for clarification and in-depth discussion.
Exercises and test simulations carried out using interactive teaching methodologies, such as the Wooclap application or Microsoft Forms.
Other information
Teaching activities will take place according to the schedule published on the website of the Degree Program in Medicine and Surgery.
Location: Department of Medicine and Surgery.
For information on dispensatory measures that can be implemented for students with DSA and/or disabilities, see the page: http://www.unipg.it/disabilita-e-dsa
Learning verification modality
The exam consists of a written test comprising 52 multiple-choice questions covering all topics of the syllabus. The test will be graded by awarding 0.6 points for each correct answer, 0 points for each unanswered question, and applying a penalty of -0.15 points for each incorrect answer.
The written test will assess detailed knowledge of the functional properties of macromolecules and metabolic reactions, including the chemical structures of the compounds involved, the mechanisms regulating these reactions, and the integration of metabolism among the different tissues of the organism.
After passing the written test, students are given the opportunity to take an oral examination covering all course topics. The oral exam aims to evaluate the level of subject knowledge as well as the ability to make connections and integrate knowledge, also in relation to the future medical profession. The oral exam will also assess the student’s communication skills and appropriate use of scientific terminology.
