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 liver

Cells: 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)
