HTHSCI 1LL3 Lecture Notes - Lecture 11: Ketone Bodies, Glycogenolysis, Glycerol
Document Summary
Circulation: hormones, nutrients, waste products are transported through the body by the circulatory system, products of digestion go to the liver (water-soluble) or into the blood (through the lymphatic system if fat- soluble) Metabolic wastes: catabolism (breakdown) produces co2, which must be removed, breakdown of proteins produces nitrogen which must be disposed of, anabolism is buildup, eg protein translation from individual amino acids. Waste elimination: the respiratory system disposes of co2, the urinary system eliminates nitrogenous wastes, unabsorbed foods are excreted from the gi tract, creates ros as a byproduct. Fed state - after a meal, we"re in the fed state from the beginning to the end of the process of absorption. Chylomicrons are the source of lipoproteins from diet, formed in the intestines. The liver forms vldls with triglycerides and protein and cholesterol, for. The source of triglycerides in vldls is excess carbohydrate and protein that has. Fed state - lipoproteins transport through the blood been converted for storage.
