Educational objectives
Module: GENERAL AND CELLULAR BIOLOGY
-------
The course in Cell Biology (I and II) aims to provide the student with the main principles that determine the organization and function of the cell. Basic knowledge about the biology of prokaryotic and eukaryotic cells (animals and plants) will be provided, as well as the structure and function of various cellular compartments, energy metabolism, the processes of cell division and the main techniques used to study of cells. The course will also address the topic of the origin of life on our planet and the evolution of the cell.
Syllabus
Module: GENERAL AND CELLULAR BIOLOGY
-------
The origin of life on our planet. The origin of the cell. General properties of living organisms, evolution, complexity, cellular organization, nutrition and metabolism, variability, principles of classification, species concept, taxonomic categories.
The unit cell structure and function of living organisms. Prokaryotic and eukaryotic cell. Techniques for the study of cells: optical microscopy, electron microscopy, fixation, inclusion, dyes, autoradiography, immunocytochemistry.
The macromolecules of the cell.
Cell membranes: structure and functions. Extracellular matrix. Cell wall of bacterial cells and plant cells: chemical constituents and properties. The Wall function and relationships between structure and function in various life stages of the cell, synthesis and assembly of wall components.
Features and functions of the endomembrane system: the endoplasmic reticulum, Golgi apparatus, exocytosis, endocytosis, lysosomes. Vacuole: ontogeny, composition of the vacuolar juice; functions of the vacuole.
Glycolysis and fermentation (elements).
Mitochondria: structure and function, respiration and the chemiosmotic theory, role in the process of cell death.
Plastids: structure and function of chloroplasts, chromoplasts, amyloplasts. Stages of photosynthesis (general concepts). Interconversion and differentiation of plastids.
Comparison mitochondrion-chloroplast; endosymbiotic hypothesis.
Peroxisomes.
Cytoskeleton: structure and function of microtubules, microfilaments, intermediate filaments. Centrioles, cilia and flagella. Cell movement and cellular contractility.
Nucleus: structure and function. Nuclear envelope, chromatin organization, euchromatin and heterochromatin, chromosomes, nucleolus.
Ribosomes. Structure and function. General aspects of protein synthesis. Principles of sorting of proteins.
Exam methods
Module: GENERAL AND CELLULAR BIOLOGY I and II
The exam will be divided into two parts, one at the end of the first semester and one at the end of the second semester. It will consist of a written test (multiple choice). Only students who pass the test in the first half will have access to the second part of the exam. All the others will have to complete the whole exam (regarding the program of first and second semester) in a single test. It is to the teacher to decide whether oral examination is required.
