Syllabus

D1 - Knowledge and understanding.
Students taking this course will gain in-depth knowledge of enzymes, their definition, and their classification. They will be able to understand the critical role enzymes play in biological reactions and industrial applications. In addition, participants will have a solid understanding of enzyme thermodynamics, including the fundamental concepts of free energy and the spontaneity of reactions. This knowledge will enable them to understand the activation energies and kinetic barriers involved in enzymatic processes.

D2 - Ability to apply knowledge and understanding.
Students will be able to apply their theoretical knowledge to analyze enzyme kinetics. They will be able to interpret and use the Michaelis-Menten equations and other derivatives, as well as understand the kinetic models of enzyme inhibition. With these skills, students will be able to evaluate the factors that influence the enzymatic reaction rate and determine the kinetic parameters such as Km, Vmax, kcat, etc. They will learn to interpret experimental data using Lineweaver-Burk plots and use this information to understand the kinetic behavior of enzymes.

D3 - Making judgments.
Students will develop the ability to critically evaluate enzyme applications in diverse industrial contexts, such as food, drug, and biofuel production.

D4 - Communication skills.
Students will be able to communicate the results of their analyzes clearly and effectively, both verbally and in writing. They will be able to present technical information in an accessible way even to a non-expert audience, demonstrating scientific communication skills.

D5 - Learning ability.
Students will be able to synthesize the information learned during the course and connect it to broader concepts in the industrial application of enzyme catalysis. They will be able to critically address complex problems related to enzyme kinetics and develop new solutions based on their knowledge and skills. In addition, students will develop the ability to learn independently, staying informed about the latest discoveries and innovations in the field of enzymology and related industrial applications.

The evaluation will be based on an oral interview, carried out based on a paper developed on laboratory experiences.

The knowledge of the topics listed in the program and the ability to apply the acquired knowledge must emerge from the thesis and subsequent oral interview. The evaluations are expressed in thirtieths, according to the following criteria:
-Excellent (30 -30 cum laude): excellent knowledge of the topics, excellent language skills, excellent analytical skills; the student can brilliantly apply theoretical knowledge to concrete cases.
-Very good (27 -29): good knowledge of the topics, remarkable language skills, good analytical skills; the student can apply theoretical knowledge to concrete cases correctly.
-Good (24-26): good knowledge of the main topics, good command of the language; the student can apply theoretical knowledge to concrete cases.
- Satisfactory (21-23): the student does not show full mastery of the main topics of the teaching, even if he possesses the fundamental knowledge; however, he shows satisfactory language skills and sufficient ability to apply theoretical knowledge to concrete cases.
- Sufficient (18-20): minimum knowledge of the main teaching topics and technical language, limited ability to adequately apply theoretical knowledge to concrete cases.
- Insufficient (<18): the student does not have an acceptable knowledge of the various topics of the program.

This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development (SDGs)
