METABOLISM IS NETWORK REACTION… 5

A protein interaction network for yeast (Saccharomyces cerevisiae) Dots represent individual proteins, colored according to function. Solid lines represent interactions between proteins. The colored clusters identify the large number of genes involved in metabolism.

Carbohydrates • Energy Metabolism – catabolism of glucose during cellular respiration yields ATP for energy-requiring activities – glucose stored as glycogen in the liver and muscle cell fiber 23

GLUKONEOGENESIS 24

HORMONAL CONTROL OF FAT METABOLISM Insulin => lipogenesis and inhibits lipolysis and decreases hormone-sensitive lipase which breaks down adipose triglyceride n Thyroxine => increases fat metabolism through increased cellular metabolism n Glucocorticoids, adrenocorticoids => increased rate of mobilization n Growth hormone => potent lipolysis effects n 25
