PROCESSI BIOCHIMICI ED APPLICAZIONI BIOTECNOLOGICHE AGROALIMENTARI

Provide knowledge about primary and secondary metabolism in plants and their importance in physiological regulation. Provide specific knowledge of Biochemistry applied to the study of plant response to hormones and biotic and abiotic stresses and on agro-food biotechnology applications. In particular, and with reference to the Dublin Descriptors, the course aims to provide the following knowledge and skills.

Knowledge and understanding

At the end of the course, the student will know, from a biochemical perspective, the main primary and secondary metabolites of plants and microorganisms, their impact on plant productivity and their possible pharmacological and nutritional use.

Ability to apply knowledge and understanding

Individual and group exercises, aimed at verifying the understanding of the concepts covered by the course. Autonomy of judgment Administration of ongoing formative tests aimed at self-assessment of understanding and learning of teaching units already completed; conscious evaluation of teaching.

Communication skills

The student will strengthen the technical language of biochemistry and communication skills through interactions with the teacher and colleagues during the course.

Learning skills

The student will be able to update and expand their knowledge by independently drawing on texts, scientific articles and online platforms.

The course includes 49 hours of frontal lessons (or distance learning) and 14 hours of classroom exercises through presentations and participatory debates among students on research, case studies or topics related to the course topics.

To ensure equal opportunities and in compliance with current laws, interested students can request a personal interview in order to plan any compensatory and/or dispensatory measures, based on the educational objectives and specific needs. It is also possible to contact the CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSA) contact teacher of the Department, Prof. Giovanna Tropea Garzia and Prof. Anna De Angelis.

The learning assessment will be oral and will focus exclusively on the topics covered in class. If circumstances warrant, it may also be administered online. The questions are designed to assess the student's knowledge of the syllabus.
The final evaluation (exam grade) will be based on the relevance of the answers to the questions asked, the quality of the content, the ability to connect the topics covered in the program, the ability to formulate examples, the student's command of technical language, and his or her overall expressive ability.

Date appeals

The exam dates will be published on the Department website.
