Abstract
This study it has for objective to describe the mitochondria as one organelle essential in the cellular physiology, as well as its structural factors, a descriptive study of bibliographical revision by means of database of articles of scientific literature was carried through: Bireme, LILACS, SciELO, PubMed and MEDLINE. The sample constituted of 21 (twenty and one) articles, amongst these, had been selected 11 (eleven) articles for basic theoretical recital (excellent group 1) and 2 (two) articles complementary theoretical recital (excellent group 2). 8 (eight) articles had only been discarded of the study (not excellent group) for the criterion “thematic relevance”. On the basis of the findings, are concluded that the mitochondria possess diverse functions essential for the functioning of the cells human beings and rocking to bimolecular, amongst them, the energy production (ATP), a factor of great importance for the activities of the organism.
