Because Pepsin is the active form of a protein manufactured in the stomach.
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.
An enzyme called a protease would digest proteins. Examples would be pepsin and trypsin.
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.
Starch and glycogen would not be able to be digested and sugar would not be able to be formed.
If pepsin, an enzyme that breaks down proteins, is added to sodium hydroxide (NaOH), a strong base, the high pH of the NaOH will denature and inactivate the pepsin enzyme. Denaturation is the process where the protein loses its shape and function due to changes in pH, temperature, or other conditions. This would prevent pepsin from being able to digest proteins in the presence of NaOH.
Pepsin activity would decrease and at a very low temperature pepsin would be inactive.
Pepsin activity would decrease and at a very low temperature pepsin would be inactive.
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.
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.
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)
the pepsin would become innactive
