What is the chief bile pigment Where does it come from?
Bile (from latin bilis), or gall, is a dark-green-to-yellowish-brown fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile) and stored and concentrated in the gallbladder.
What is the principal enzyme for breaking down carbohydrates?
Amylase is essential for the digestion of carbohydrates. It breaks down starches into sugars. Amylase is secreted by both the salivary glands and the pancreas.
Why is it necessary for the stomach to be acidic?
The acidity activates the protein-digesting enzyme (pepsin) in the stomach which is required alongside hydrochloric acid to commence the splitting apart of protein molecules. The acid unravels proteins to enable the pepsin enzyme to get to work.
What is the principal enzyme?
Explanation: The principal enzyme involved in DNA replication is called DNA polymerase. The enzyme joins nucleotides to synthesize a new two strand of DNA. DNA replication is called proofreads because each new DNA molecule is made up.
What are the 4 types of enzymes?
Types of enzymes
- Amylase breaks down starches and carbohydrates into sugars.
- Protease breaks down proteins into amino acids.
- Lipase breaks down lipids, which are fats and oils, into glycerol and fatty acids.
Which foods are high in enzymes?
Foods that contain natural digestive enzymes include pineapples, papayas, mangoes, honey, bananas, avocados, kefir, sauerkraut, kimchi, miso, kiwifruit and ginger. Adding any of these foods to your diet may help promote digestion and better gut health.
What is the enzyme that digests starch?
enzyme amylase
What chemical breaks up large fat droplets?
Emulsification greatly increases the surface area of the fat on which the lipase can actually act on. As a result, lipase is now in a position to begin digesting the ester bonds of the lipids efficiently. With the help of colipase, lipase binds onto the surface of these emulsion droplets and begins breaking them down.
What product is formed when protein is broken down by the enzyme?
Protease enzymes break down proteins into amino acids.
What is the end product of protein breakdown?
The end product of protein must be broken down into amino acids. So, the correct answer is ‘Amino acids’. Note: Digestion is the breakdown of large insoluble food molecules into water-soluble food molecules so that they can be absorbed by the blood.
What is the end product of protein in the body?
amino acids
Is protein metabolism an end product?
The major end-product of protein catabolism in animals is ammonia (Campbell, 1973). This compound may be excreted as ammonia itself, urea or uric acid, depending on the animal. The nature of the major nitrogenous end-product of a species depends on the availability of water.
What is the first body organ to receive the end product of protein digestion?
Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.
Is ammonia a byproduct of protein?
When you eat proteins, the body breaks them down into amino acids. Ammonia is produced from leftover amino acids, and it must be removed from the body. The liver produces several chemicals (enzymes) that change ammonia into a form called urea, which the body can remove in the urine.
What is the end product of protein hydrolysis?
Proteins are biopolymers made up of by joining together of amino acids with the help of peptide bonds. When proteins are acted upon by digestive proteolytic enzymes in the gut the peptide bonds are hydrolyzed and a mixture of amino acids is obtained.
What are the product of hydrolysis of protein?
Where does hydrolysis of proteins occur?
The proteolytic enzymes of the pancreas are responsible for the major portion of protein hydrolysis, which occurs within the lumen of the gastrointestinal tract.
