How does butter in your food gets digested and absorbed in the body? |
|
Answer» Digestion of fats: Butter is a fat product and gets digested in the small intestine. The bile juice secreted by the liver contains bile salts that break down large fat globules into smaller globules, so as to increase their surface area for the action of lipase. This process is referred to as emulsification of fats. After this, the pancreatic lipase present in the pancreatic juice and the intestinal lipase present in the intestinal juice hydrolyse the fat molecules into triglycerides, diglycerides, monoglycerides, and ultimately into glycerol. `"Fats "overset("Pencreatic")underset("lipase")rarr" Triglycerides + Diglycerides"` `"Diglycerides and monoglycerides "overset("Lipases")rarr" Fatty acids + Glycerol"` Absorption of fats: Fat absorption is an active process. During fat digestion, fats are hydrolysed into fatty acids and glycerol. However, since these are water insoluble, they cannot be directly absorbed by the blood. Hence, they are first incorporated into small droplets called micelles and then transported into the villi of the intestinal mucosa. They are then reformed into small microscopic particles called chylomicrons, which are small, protein-coated fat globules. These chylomicrons are transported to the lymph vessels in the villi. From the lymph vessels, the absorbed food is finally released into the blood stream and from the blood stream, to each and every cell of the body. |

Which of the following is the primary absorptive process in the large intestine?A. Active transport of `Na^(+)` from the lumen to the bloodB. Absortion of amino acids and fructoseC. Active transport of potassium from the lumen to the bloodD. Active absorption of `HCO_(3)^(-)` into the blood |
|
Answer» Correct Answer - A The mucosa of large intestine has a high capability for active absorption of sodium ions which create a gradient for chloride ions absorption as well. This forms an osomotic gradient across the large intestinal mucosa causing absorption of water. |

Effect of some compounds (present in partially digested food) on pancreatic seretion is depicted in the bar graph. Compounds 1,2 and 3 r4epresent. A. `{:(1,2,3),("Acid","Fat","Salt"):}`B. `{:(1,2,3),("Salt","Peptone","Fat"):}`C. `{:(1,2,3),("Acid","Fat","Peptone"):}`D. `{:(1,2,3),("Pepsin","Acid","Fat"):}` |
|
Answer» Correct Answer - C Pancreatic secretion contains multiple enzymes for digesting all of the three majuor type s of food, proteins, carbohydrartes and fats. When highly acidic food enters the small intestine, it stimulates secretion of lrge quantities of water solution of sodium bicarbonate by pancreatic ductal epithelium. The presence of proteoses and peptones and long chain fatty acis in the chyme results in secretion of pancreatic difgestive enzymes by the acinar cells and its effect is even more pronunced than that caused by vagal stimulation. |
