Why does pepsin not digest sucrose?
Sucrose is a type of carbohydrate. Pepsin is a protease, so it can only digest proteins, because enzymes are specific to one kind of molecule. Sucrose would be broken down by a carbohydrase.
Name of the protein that can destroy protein?
An enzyme called a protease would digest proteins. Examples would be pepsin and trypsin.
What Gastric juice digest proteins?
There are two things in gastric juices, Pepsin and hydrochloric acid. If one is alone, it would not do any digestion of proteins. But together, they can digest proteins.
Which enzyme convert protein into amino acids?
Pepsin (excreted by glands in the stomach) digest proteins into polypeptides in the stomach, whereas the trypsin (excreted by pancreas in the pancreatic juice) digest proteins into polypeptides in the small intestine. Then the erepsin (excreted by pancreas in the pancreatic juice) further digest them into amino acids.
What would happen if enzyme amylase is absent in saliavary gland secretions?
Starch and glycogen would not be able to be digested and sugar would not be able to be formed.
What effect would decreased incubation temperatures have on pepsin?
Pepsin activity would decrease and at a very low temperature pepsin would be inactive.
What effect would decrease incubation temperature have on pepsin activity?
Pepsin activity would decrease and at a very low temperature pepsin would be inactive.
What effect would decreased incubation temperature have on pepsin activity and why?
Pepsin activity would decrease. At a very low temperature pepsin would be inactive.
Why doesn't protease digest itself?
Good question, but once you think about it, the answer is quite simple. Protease needs to grab on to something (a protein) in order to digest it. It cannot grab onto itself. More specifically, proteases are designed to recognise specific proteins or protein sequences which they bind to and then cut or break up the protein at. The protease cannot turn around on itself in order to catalyse this reaction. This answer isn't quite correct. In your answer you act as if there is only one pepsin molecule. If that was the case then indeed pepsin cannot 'grab onto itself'. However the question should have been : why doesn't pepsin digest other pepsin molecules. To find the answer to that you would have to look closer into what kind of atoms the molecules are made of and why they do not 'react' with eachother.
What are the enzymes in a cell that help to break material down in a cell?
those enzymes would be in the lysosomes of the cell they would be things like amylase (breaks starch down) and pepsin (amino acids) and things like lipase (lipids)
What would most likely happen to pepsin that traveled with the food from the stomach to the small intestines?
the pepsin would become innactive
Why is pepsin stored under pepsinogen?
Pepsinogen becomes pepsin when activated by the stomach's Hydrochloric acid. This protein digest proteins, it could not be produced nor stored in the body's cells in its active form because it would destroy the cell that made it. The cells protect themselves by producing and storing the enzyme in an inactivated form.
