Cell Biology

Recommended Prerequisites

Cellular and Molecular Biology (basic level)

Teaching Methods

Theoretical classes supported by visual material (Powerpoint presentation) and in which the participation of students is encouraged with the posing of questions and correlation of knowledge. Use of quizzes where appropriate

Laboratory classes aiming to help the student to understand the organization and functioning of cells and to get in touch with cellular and molecular biology methodologies

Learning Outcomes

The main objective is the study and the understanding of the cellular and molecular mechanisms that occur in the cytoplasm and in cell organelles and the way in which these processes are conjugated and contribute, through the inter- and intracellular signaling pathways, to the maintenance of the functional activity of the cell and to the survival of the multicellular organism.

The program of this unit is developed under the following themes:

i) cell composition and molecular organization;

ii) intracellular organelles: structure and functional dynamics;

iii) cellular synthesis and transport of molecules: intracellular trafficking;

iv) cell communication: signal transduction mechanisms between cells and between cells and the environment; regulation of cell function;

v) Cell cycle.
