Course objectives
The aim of the subject Biochemistry I is to gain knowledge about the basic metabolic processes and pathways taking place at the cellular level.
Understanding these processes is the basis for understanding metabolism at the tissue and organ level, which is studied in the follow-up subject Biochemistry II.
Learning outcomes
In the end of the course students will:
- understand the meaning of basic chemical terms (pH, osmolality, electrolyte, buffer, etc.) and apply this knowledge when describing the properties of body fluids.
- describe the role of macro- and microbiogenic elements in the organism
- discuss the properties and function of enzymes
- describe basic catabolic and anabolic pathways of carbohydrate, lipid and protein metabolism, and their relationships.
- understand the principles of energy production, utilization and deposition at the cellular level.
- explain the function of cell membranes and the principle of compartmentalization at the cellular level and the transport processes on the membrane.
- describe protein synthesis, starting with the replication and transcription, translation and post-translational modifications. Understand the relationship between protein structure and function.
- explain the function of hemoglobin in oxygen transport and maintaining acid-base balance.
- discuss the principles of some diseases at the molecular level.
