Learning Outcomes
Aims of the course: To help the students understand the basic principles of cell biology, the importance of the cell structure to its functions and the roles of both the subcellular organelles and the major biological macromolecules. To achieve these goals, the course presents various areas of cell biology, i.e. starting with the presentation of the chemistry of the cells and the biosynthesis of its macromolecules (DNA, RNA, proteins etc) and continuing into the structure of the mambraneous cell organelles, the pathways of intracellular transport, energy production and cell communication. Special emphasis will be given in aspects that are usefull to pharmacy students, e.g. the cellular and molecular basis of disease and drug effects on the cell structure and function. Skills: Familiarization with key concepts of cell biology.
General Competences

  • Retrieve, analyse and synthesise data and information, with the use of necessary technologies
  • Be critical and self-critical
  • Advance free, creative and causative thinking

Introduction to the Cell: Life and its study. Introduction to the cell and its components. Cell theory. Observing cells under a microscope. Similarities and differences between cells. The chemical composition of the cells: Chemical bonds. Characteristics and the role of water. The molecules of the cell. Structures of simple sugars, polysaccharides, fatty acids/fats/lipids, nucleic acids and proteins. Enzymes, enzymatic reactions, allosteric motor proteins and protein machines. Biological membranes, Intracellular compartments and transport: The lipid bilayer, membrane proteins (categories of membrane proteins, modes of attachment to the membranes, functions, the role of the cell cortex). Membranes carbohydrates and the importance of glycocalyx. Membrane organelles-structure and biological roles. Mechanisms of protein sorting and import to organelles (co- & post-translational translocation, the role and significance of signal sequences). The role of molecular chaperones in the protein transport across membranes, as well as on protein quality control. Vesicular transport (cargo selection, vesicle budding, targeting and docking of transport vesicles). Sectretory pathway and the role of the Golgi apparatus. Endocytosis, phagocytosis and structure and functions of lysosomes. Cytoskeleton: The role(s) of cytoskeleton. Intermedidate fillaments.

ICTs are used both in the lectures and the tutorials of the course (Powerpoint and video presentations, interactive tutorials using computer simulations, etc). The course lectures, announcements, exam results etc are regularly posted in the webpage of the course coordinator.
Course Organization
Student Assessment
Intermediate exams (A) or final exams at semester end (B). The exam structure is similar both in A & B and it constists of 20 questions where the students are asked to define whether the question is correct or wrong (0.1 point per correct answer, -0.1 point per mistaken answer) and to justify their answer (0.4 points per question). All questions are equivalent (0.5 points). Questions that have not been answered correctly by any students are withdrawn and final grade is calculated based on the grades from the remaining questions. The examination time in 1 hour
Student Assessment methods
  • Written Exam with Short Answer Questions (Summative)
