Term
| What is glycogenolysis and which hormones stimulate ut? |
|
Definition
Glycogenolysis is the catabolism of glycogen by removal of a glucose monomer through cleavage with inorganic phosphate to produce glucose-1-phosphate. This derivative of glucose is then converted to glucose-6-phosphate, an intermediate in glycolysis. The hormones glucagon and epinephrine stimulate glycogenolysis. from wikipedia |

Definition
Chylomicrons are large lipoprotein particles (having a diameter of 75 to 1,200nm) that are created by the absorptive cells of the small intestine.The chylomicrons are released by exocytosis from enterocytes into lacteals, lymphatic vessels originating in the villi of the small intestine, and are then secreted into the bloodstream at the thoracic duct's connection with the left subclavian vein. Chylomicrons transport exogenous lipids to liver, adipose, cardiac and skeletal muscle tissue where they are broken down by lipoprotein lipase into very low density lipoproteins (VLDLs). http://en.wikipedia.org/wiki/Chylomicron |
