Teaching Methodologies
Lecture (T) classes are expository using a PowerPoint slides projection In practical (TP) classes, after a brief theoretical introduction, the different chapters exercise sheets are solved. All study material is made available through the Moodle platform. Students are encouraged to participate with questions and comments during both lecture and practical classes.
Learning Results
The learning objectives in this course is to provide students with the ability to: i) understand the role of enzymes in biotechnological applications; ii) understand the properties and functions of enzymes; iii) identify the types of enzymatic catalysis mechanisms; iv) describe the biocatalysis process in unconventional means; v) model the enzyme kinetics; vi) understand and describe the main types of enzyme inhibition; vii) determine the effect of enzyme immobilization on their kinetics; viii) understand and model the main types of reactors with immobilized enzymes.
