摘要：All biological phenomena are the result of an evolutionary process. The cellular metabolism is not one exception and traces of this process can be found in modern cells. In this paper we are pointing out, through a comparative analysis, metabolic features meaningful enough as to allow us to propose a philogenetical pattern of a display of cellular metabolism and identify the main stages of it. The first model of this type was developed by F. Cordón (1990) within his “Theory of Integration Levels Units” and it is part of the development of it. The pattern we are presenting here fully agrees whith that the Cordón’s, but it is reasoned from arguments outside his theory which enables us to separate the model from the theory. Besides, to arrive at the same conclusions coming from different arguments reinforces the ones from that theory and, as a consequence, the theory itself.
