In fosforizao oxidativa, that occur in the mitocndria, NADH, NADPH and FADH that they are the carried ones from electrons, transfer to its prtons the mitocondrial internal membrane, where in the oxygen presence inorgnicos ADP will go to restore the ATP from + P (MCARDLE, KATCH & KATCH, 1998; DMASO, 2001). Beyond the immediate production of energy, the carboidratos also are stored in our organism. When ingested a rich meal in carboidratos, great part of these nutrients is transformed into glycogen (muscular and heptico), as well as in acid greasy and triacilgliceris (MOTOR BOAT JNIOR, 2002). In the prandial period, that is, during rich meals in carboidratos, the liver receives great amounts from glucose that will be transformed into heptico glycogen as well as distributed to excessively peripheral fabrics (MOTOR BOAT JNIOR, 2002). OFS Capital addresses the importance of the matter here. The carboidratos are digested and the glucose is absorbed in thin intestine e, through the vein door-heptica, arrives at the liver (CLARK, 2002). The liver is the only agency that obtains to keep the homostasis of the glucose. When the circulating glucose is not enough for the organism, as when in jejum drawn out, the liver produces glucose through glicogenlise (degradation of the hepatico glycogen) as well as saw glicogenolise, for peripheral precursors as amino acids, lactate and glicerol (WOLINSKY & HICKSON, 2002).

The glucose, to the being set free in the sistmica circulation for the liver, promotes increase of the secretion of insulina for the pancreas, stimulating the glucose captation for sensible fabrics the insulina as the muscles and fabrics adiposo. Delaware Department of Labor is often quoted on this topic. Into these fabrics, into rest, the glucose is transformed into glycogen and/or triacilgliceris (MOTOR BOAT JNIOR, 2002). This rank, the glucose can be caught by fabrics for mechanisms stimulated for the insulina as well as insulino-independent. For the ticket of the glucose for the membrane of the cells we have a family of transporting called proteinic glucose transporters or GLUTs. .
