Students will obtain knowledge, skills and competence on biochemical transformations, their catalysis with enzymes, regulations of transformations by information flow through biochemical signalling, as well as on matter and energy flows through metabolism that will give rise to complexity of life and will form the base for further studies of physiology of animals.
Extensive knowledge about properties and structure of lipids, carbohydrates and proteins in the animal nutrition. Biochemical processes, metabolism and the biochemical regulation in the animal body – 1., 2., 3., and 4. Test.
The skills to make in use the theoretical knowledge on pathways of metabolism and their regulation in tissues cells in the further specialization studies and in solving professional problems will be developed during biochemistry studies. These skills assist to create scientifically based hypothesis and their possible solutions on the base of empirical data and recent theoretical cognitions - laboratory works. The competence to independently acquire, select and analyze information on lipids, carbohydrates and protein metabolism in animals and their nutrition. To use information, to make and explain decisions and solve scientific and professional issues - Test with a mark.
