Lecture 40: Peripheral Endocrine Glands - Fuel Metabolism Reading: chapter 19, pgs 701-716 (5 th edition 719-733) Metabolism All of the chemical reactions that occur within cells Fuel metabolism (aka intermediary metabolism) Reactions involving energy-rich organic molecules: carbohydrate, fat or protein. Anabolism ( NET CONSTRUCTION ) - manufacture of macromolecules from smaller subunits i.e. aa -> protein - storage of nutrients for later use in energy production ( LIPIDS OR MUSCLE PROTEIN , E . G .) Catabolism ( NET DEGREDATION ) - hydrolysis of macromolecules into small subunits i.e. glycogen ->glucose - oxidation of smaller subunits to yield energy for ATP production Reaction in fuel metabolism: - glycogensis: glucose is stored as glycogen, blood glucose goes down - glycogenolysis: glycogen is broken down to glucose, blood glucose goes up - gluconeogenesis: amino acids are interconverted to glucose, blood glucose goes up - protein synthesis and degradation - fat synthesis and degradation Major pathways in fuel metabolism
