Annotation -
The subject is devoted to the study of cellular processes at the molecular level and is conceived so that the students receive the basic knowledge for understanding the complex functioning of eukaryotic cells in multicellular organisms.
Last update: Rumlová Michaela (30.01.2018)
Aim of the course -

Students of this course will understand the basic principles of eukaryotic cell functioning in multicellular organisms. Students will comprehend the structural and functional organization of eukaryotic cells, intracellular and vesicular transport of proteins to the organelles and their incorporation into biological membranes, basis of cell communication with the environment and signal transduction, cell cycle regulation, cell differentiation, programmed cell death, and integration of cells into tissues.
