FAQ: Which Of The Following Is A True Statement About The Digestion And Absorption Of Proteins?

What enzyme is released by the stomach to digest protein quizlet?

Proteins are digested in the stomach. The enzyme pepsin breaks down proteins in the stomach. The pepsinogen that is created by the chief cells in inactive until it comes in contact with the hydrochloric acid. It then turns into pepsin and breaks down the proteins.

Which of the following is true about digestion and absorption of proteins?

Which of the following accurately describes a process occurring during the digestion and absorption of protein? Proteins are chemically broken down into smaller units in the stomach, but must be further broken down in the small intestine before absorption.

Which statement regarding digestion and absorption is true?

So, the correct answer is ‘ Fructose and amino acids are absorbed through intestinal mucosa with the help of carrier ions like Na+’.

What is the digestion and absorption of protein?

The three main proteolytic enzymes produced naturally in your digestive system are pepsin, trypsin and chymotrypsin. Your body produces them to help break down dietary proteins like meat, eggs and fish into smaller fragments called amino acids. These can then be properly absorbed and digested.

What enzyme is released by the stomach to digest protein?

Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.

Which of the following is not a protein digesting enzyme?

pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids. Hence, Lipase enzymes are not useful in the digestion of proteins. So, the correct answer is ‘Lipase’.

What organ does the chemical digestion of proteins begin?

The digestion of protein starts in the stomach, where HCl and pepsin break proteins into smaller polypeptides, which then travel to the small intestine.

What are the steps of protein digestion?

Protein Digestion and Absorption

  • 1 – Protein digestion in the mouth. Unless you are eating it raw, the first step in digesting an egg (or any other solid food) is chewing.
  • 2 – Protein digestion in the stomach.
  • 3 – Protein digestion and absorption in the small intestine.

How are proteins absorbed in the digestive system?

In adults, essentially all protein is absorbed as tripeptides, dipeptides or amino acids and this process occurs in the duodenum or proximal jejunum of the small intestine. The peptides and/or amino acids pass through the interstitial brush border by facilitative diffusion or active transport.

Where does digestion start?

Digestion begins in the mouth. The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.

What is absorbed in the Lacteals?

There are blood capillaries and special lymph capillaries, called lacteals, in the center of each villus. The blood capillaries absorb most nutrients, but the fats and fat-soluble vitamins are absorbed by the lacteals. The lymph in the lacteals has a milky appearance due to its high fat content and is called chyle.

How is digestion regulated?

The brain and the endocrine system control digestive processes. The brain controls the responses of hunger and satiety. The endocrine system controls the release of hormones and enzymes required for digestion of food in the digestive tract.

How do you know if you are not digesting protein?

Symptoms of protein malabsorption include indigestion, gas, bloating, acid reflux, GERD, constipation, diarrhea, malabsorption, nutrient deficiencies, hypoglycemia, depression, anxiety, trouble building muscle, ligament laxity.

What is digestion and absorption?

Digestion is the chemical breakdown of the ingested food into absorbable molecules. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small intestine into the cell, then into the blood.

Which of the following is in the correct order for protein digestion?

Which of the following details the correct order in which proteins are digested? Pepsin breaks down peptide bonds in the stomach, then the pancreatic enzymes complete the digestion in the intestines. The pancreatic enzymes break down peptide bonds in the stomach, then chymotrypsin completes the digestion in the liver.
