Cell biology is an interdisciplinary subject integrating the fields of biochemistry, molecular cell biology and genetics. The aim of the course is to gives basic knowledge about the structure and function of cells and cellular components. The different modules of the course will examine different areas of cellular biology including structure and function of prokaryotic and eukaryotic cells, membrane and organelle structure and function, chemical composition of the cell, cell organelles and cellular communication. In this course, we will also examine the methods to fractionate cells and cellular components. The other important aspects of cell biology that will be discussed in the course includes: mechanisms behind organelle transport and secretion;; the structure and function of enzymes and kinetics of enzyme reactions; cell communication; intercellular contacts, cell surface receptors; extracellular matrices; signals over the plasma membrane, receptors, and cell signaling; the organisation and structure of the cell nucleus, chromatin and chromosomes.
