Learning Outcomes
BIOCHEMISTRY I
At the end of the course the student must be able to describe, in molecular terms, the structure of biological matter, knowing how to recognize the role of the structure on the functionality of the macromolecules themselves.
He will also have to show mastery of the main signal transduction mechanisms, knowing how to focus their role in cell signaling processes.
BIOCHEMISTRY II
Know and explain at the molecular, subcellular, cellular and tissue level the biochemical mechanisms involved in the processes of: digestion, absorption, transport, storage, catabolism, interconversions, excretion, biosynthesis of: carbohydrates, amino acids and proteins, lipids, nucleotides, heme group, also in relation to different functional states of the organism.
Molecular Biology
Understanding the molecular mechanisms that regulate gene expression and their modulation in pathology
Prerequisites
Passing exams in Chemistry and Biochemical Preparation.
Attendance of biology and anatomy exams.

Additional Information
Learning control: collegial discussion of the topics of the program and of the numerical exercises proposed during the lessons. Course is supported in the web site DIR section with appropriate material to verify the degree of initial preparation and learning “in itinere”. There are traces of discussion and verification of the study of the topics covered in the course. There are also tests with open-ended and multiple-choice questions and numerical exercises for the evaluation of the study. The teacher answers only to e-mail signed and coming from the domain: matricola@studenti.uniupo.it.
Assessment Methods
The exam relating to the ENTIRE INTEGRATED COURSE can be taken at the end of the entire course.
The exam takes place in 1) written an 2) oral form, see relevant information in the individual modules. The learning assessment method will be the expression of a global judgment of the integrated course. Written exam of Biochemistry 1, as well as for the written part of Molecular Biology, the grade remains valid until September of the current academic year.
Students with a sufficient grade will then be able to take the oral part of Biochemistry 2.
Examination in oral part, see the Biochemistry 2 section of the course. Written exam for both BIOCHEMISTRY 1 and MOLECULAR BIOLOGY must always be re-taken in subsequent sessions, in the event that the oral exam is not passed. There are frequent self-assessment tests and an ongoing evaluation test.
