CELLS HAVE SAME CAPACITY FOR BUILDING AND DESTROYING
Posted by Surgery on Jul 8, 2008
The cell contains the information necessary for its function and survival. This information is stored in the chromosomes as genetic material named genes. For each particular cellular function, a specific set of genes is expressed to carry out specific tasks (Fig. 1-1 Lopressor ). The expression of these genes is modulated by the cellular state and the milieu in which the cell resides. The cellular environment is constantly modified by many factors, including the availability of nutrients, oxygen tension, the occurrence of harmful substances, and the presence of other cells. Thus, the particular physiological state of the cell is the response to a unique environment, resulting in a particular pattern of gene expression. When the cell moves from one physiological state to another, macromolecules that define the prior condition are degraded and replaced by a different set of molecules. When environmental conditions are not optimal for function or survival (e.g., high temperatures Lopressor), damaged cellular components (e.g., proteins) are repaired or destroyed.
