Learning objectives
The student is asked to understand and learn the content of the course. Attendance to lessons, which is mandatory, will allow the student to acquire appropriate skills to describe, communicate, understand and applicate knowledge of the main bio-molecules (proteins, nucleic acids, enzymes and co-enzymes); the mechanisms of metabolic energy production, energetic and structural homeostasis of living cells.
Prerequisites
Before taking the exam of "Biochimica e Biologia Molecolare" students have to pass:
Chimica e propedeutica Biochimica

Teaching methods
The course will be held through lectures to Students either in classroom (“in presenza”) or in synchronous-streaming (“in telepresenza”) on Teams platform.The course will be held with oral lectures and seminars to deep single issues, and will make use of multimedia systems. During the lessons, students will have the opportunity to discuss the key aspects of the course. Teachers will be available throughout the duration of the course to answer questions and support students during their training with individual meetings by appointment. Lectures will be supported by slide presentations, which will be available to students on Elly platform (https://elly2020.medicina.unipr.it/).
Assessment methods and criteria
Multiple choice test. If the test is successful, the student can ask to proceed with the grade recording or to take an integrative oral examination. In the event that the student's preference falls on the second option, the final grade will be the average of the results reported in the two tests. In case of the persistence of the COVID-19 health emergency, the exams will be conducted remotely, by means of a structured written test (by Teams and/or Elly). The test consists of 6 open-ended questions on all the course contents (reference texts + documents uploaded to Elly during the course).
Students with SLD / BSE must first contact Le Eli-che: support for students with disabilities, D.S.A., B.E.S. (https://sea.unipr.it/it/servizi/le-eli-che-supporto-studenti-con-disabilita-dsa-bes).
