Question

Part C The Process of Lipid Digestion The process of lipid digestion begins even before you take your first bite of food. Just the smell of food can begin digestive juices flowing. The most common lipids found in foods are primarily in the form of triglycerides. These lipids are hydrolyzed during digestion to yield monoglycerides, glycerol, and free fatty acids. Rank the events from taking a bite of food rich in lipids to triglycerides being released to cells. Hints Reset Help As chyme enters the duodenum of the small intestine cholecystokinin stimulates the galbladder to contract and secrete bile and stimulates the secretion of digestive enzymes from the pancreas Inside components of micelles re-tonm to create chylomicrons that enter the lymph short-chain fatty acids enter Fats are broken up into smaller droplets in the stomach, and chiet cells release gastric lipase, Fatty acids, Solid fatS melt during mastication, and lingual lipase begins digestion Blle from the gallbladder emulsifies large at globules into smaler ones in the smal intestine. Pancreatic lipase hydrolyzes tiglycerides into and other lipids form micelles, and micelles transport monoglyc cerdes, glycerol,products of and fatty acids. lipid digestions which hydrolyzes of triglycerides. directly. You take a bite of food rich in lipids Triglycerides are released to cells aided by lipoprotein lipase.

Explanation / Answer

1.You take bite of food rich in lipids.

2. Sokid fats melt during mastication and lingual lipase begins digestion of triglycerides.

3. Fats are broken up into small droplets in stomach and chef cells release gastric lipase which hydrolyses some triglycerides.

4. As the chyme enters the duodenum of small intestine, cholecystokinin stimulates gall bladder to contract and release bile and stimulated secretion of digestive enzymes from pancreas.

5. Bile from gall bladder emulsifies large fat globules into smaller ones in small intestine.

6. Pancreatic lipase hydrolyses triglycerides into monoglycerides, glycerol and fatty acaci.

7. Fatty acids and monoglycerides form micelles and micelles transport products of digestion to enterocytes.

8. Inside enterocytes components of micelles reform to form chylomicrons that enter the lymph. Short chain fatty acids enter blood directly.
