INTERMEDIARY METABOLISM
What??
Fate of dietary components after digestion and absorption. Flow of molecules through metabolic pathways and interaction between these pathways.Liver:
Primary metabolic organ - functions to regulate blood concentration of most metabolites (glucose, amino acids, etc.)Hepatic Portal Vein:
vein that caries absorbed nutrients from G.I. tract to liverCells:
the level at which metabolic pathways occur.*glycolysis
gluconeogenesis
lipolysis
*Krebs (TCA, citric acid) cycle
b
-oxidation*Electron transport
anaerobic
= O2 not present (cytoplasm)aerobic
= O2 present (mitochondria)
