Integrated course unit module: BIOCHEMISTRY AND MOLECULAR BIOLOGY

Learning objectives

The student will be expected to understand and learn the course content. Attendance in the course, which is compulsory, will enable the student to navigate the broad discipline and the acquisition of adequate skills to be able to describe, communicate effectively, and comment with independent judgment:

- the characteristics, functions, structure, and metabolic role of the proteins myoglobin and hemoglobin

- the characteristics, functions, structure and regulation and metabolic role of enzymes;

- the mechanisms of metabolic energy production and the energy and structural homeostasis of living cells.

Prerequisites

Before taking the exam of "Biochimica e Biologia Molecolare" students have to pass:
Chimica e propedeutica Biochimica

Course unit content

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.
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).
