- Objective (expected results of study and acquired competences)
After successful attendance of this lecture the students should be familiar with the basics of biochemical reactions like reaction order or thermodynamic aspects. The student can derive the Michaelis-Menten equation on different examples and the can determine and evaluate the Michaelis-Menten parameters. On the basis of selected examples the students can differentiate between selected inhibitions pattern and can calculate and evaluate the inhibition constants. The students can describe cooperativity and different allosteric models. The students are able to plan and make reactions with more than one substrate and evaluate the derived kinetic parameters. They should know common methods and analysis for measuring rate constants and they should be able to evaluate if they have selected the right method.
