A patient is admitted come the hospital v severe abdominal muscle pain. A scan reveals that the bile bladder has multiple stones in it, and also one is prevent the cystic duct.

You are watching: What serves as an emulsifying agent in the small intestine


Explanation:

The bitterly bladder is important because of that is storage and release the bile throughout digestion. Bile is essential in the emulsification (or break up) the nonpolar fat in the aqueous small intestinal fluid. Cystic duct obstruction would an outcome in bile being unable to with the small intestine, and also triglycerides would certainly be unable to be effectively emulsified and also absorbed.


Explanation:

The liver produce bile, i beg your pardon travels under the bile duct to it is in released right into the tiny intestine, especially the duodenum. Once the duct is no open, bile backs up and gets save in the bitterly bladder. As soon as the duct is open, once the small intestine senses the presence of food, the bitterly bladder will certainly release the bile to emulsify fats during digestion.


Explanation:

Both bile salts and also phospholipids are excreted from the bile duct right into the upper small intestine (duodenum) come emulsify lipids. They are both amphipathic molecules, which means they have actually non-polar/lipophilic end that deserve to bind to lipids and polar/hydrophilic end that deserve to bind come water, hence emulsifying the lipids that they contact.

As these compounds room excreted indigenous a single duct, small intestine motility permits them to mix with the materials of the small intestine and emulsify much more lipids 보다 they would have the ability to in a quiet environment. Small intestine motility also helps to rest up huge globules of dietary fat.

Once emulsified, dietary fat can be broken down by lipase, but lipase chin does not improve emulsification.

Example inquiry #4 : expertise Emulsification


Which organ stores the link responsible for emulsifying lipids throughout digestion?


Possible Answers:

Gall bladder


Pancreas


Small intestine


Liver


Correct answer:

Gall bladder


Explanation:

Fats are usually composed that nonpolar lipids, making them hydrophobic and insoluble. In order come digest fats, they should be grouped with each other to boost their surface ar area and allow for enzyme interaction, digestion, and absorption.

Fat emulsification is the process of raising the surface ar area of fat in the small intestine by grouping them into tiny clusters. This is the obligation of bile, a liquid developed by the liver and also stored in the gallbladder. Actual cradle of the fats is then accomplished by lipase, an enzyme native the pancreas. Spend lipids space then transported into the lacteals that the microvilli for transportation through the lymphatic system prior to entering the blood.

Example concern #5 : expertise Emulsification


Bile is produced in the __________, stored in the __________, and also released into the __________.


Possible Answers:

gallbladder . . . gallbladder . . . small intestine


liver . . . Gallbladder . . . small intestine


liver . . . gallbladder . . . large intestine


kidneys . . . gallbladder . . . small intestine


Correct answer:

liver . . . Gallbladder . . . small intestine


Explanation:

The liver is responsible for synthesizing bile salts; these salts space transferred into the gallbladder together bile. The gallbladder shop bile, i beg your pardon it climate secretes into the small intestine. Bile contributes to digestion by breaking up large fat globules, a process known together emulsification. Fats room insoluble in water, for this reason emulsification gives pancreatic lipase with much more surface area on which come act. 

Neither the spleen nor the huge intestine are relevant answers to this sentence. The large intestine helps remove undigested waste from the body, absorbs water from waste, and also produces/absorbs vitamins (due to nests of valuable bacteria that live in the huge intestine). The spleen is an organ responsible because that filtering the blood and also housing white blood cells; the is not connected in digestion.

Example question #1 : expertise Emulsification


Bile salts space amphipathic and essential for fat absorption. Which of the complying with nutrients will be challenging to absorb in a patient through an i can not qualify to secrete bile salts right into the stomach?

I. Vitamin A

II. Vitamin B

III. Vitamin C


Possible Answers:

II only


I and also II


All of these


I and III


I only


Correct answer:

I only


Explanation:

Bile salt emulsifies fat into chylomicrons to permit for absorption. Of the choices, only vitamin A is fat-soluble. Vitamins B and C space both water-soluble.

Example concern #7 : knowledge Emulsification


Bile salts emulsify dietary fats by breaking them down into smaller clusters and also creating a molecule dubbed a __________.


Possible Answers:

chylomicron


bolus


micelle


cluster


globule 


Correct answer:

micelle


Explanation:

Bile salts surround fat droplets in bespeak to develop micelles. This micelles are much more accessible to the enzymes that have the ability to rest them down further. Chylomicrons space lipoproteins the are essential in transport and metabolism of lipids.

Example concern #8 : understanding Emulsification


Bile salts make fat droplets an ext accessible to the enzyme __________.

Possible Answers:

lingual lipase


chymotrypsin


trypsin


pepsin


pancreatic lipase


Correct answer:

pancreatic lipase


Explanation:

Once huge fat clusters are damaged down through bile salt to become smaller micelles, pancreatic lipase has much more surface area to access fats. The enzymes room able to reach the fat droplet with the gaps between bile salts. Fats space not emulsified through bile yet in the mouth, so lingual lipase plot upstream that bile come hydrolize lengthy chain hydrocarbons. The other answer options are proteases.
