Pepsin becomes inactive when it reaches the small intestine where the pH is between 7 and 9. It functions best when in an acidic environment like the stomach.
When pepsin reaches the small intestine, its activity stops. The small intestine has a basic pH of 8 thereby inactivating pepsin which needs an acid environment to work in.
Pepsin activity decreases due to the neutral pH
Pepsin is active at pH1 to pH4 therefore is inactive in the small intestine where the pH is higher than 5
It is absorbed and used to break down the food that comes through the small intestine.
It replicates
food will be absorbed
the pepsin would become innactive
Yes. The precursor of pepsin is called pepsinogen; it is produced by stomach cells and then activated by the HCl in the stomach. Pepsin works best at very low pH.... e.g. acid conditions of the stomach. The small intestine has glands that produce neutralize the acid. Pepsin denatures at pH's of 5,0 or higher..... so effectively it is neutralized when the chyme enters the small intestine.
The enzyme that catalyzes the digestion of peptides in the small intestine is pepsin. Pepsin is released by the mucosal lining of the stomach.
Food enters the small intestine first. It enters the duodenum in the small intestine.
pepsin and all other digestive enzymes are neutralized by the small intestine
Yes.
expressed in the stomach but not expressed in the small intestine
Small intestine is where the food enters the blood.
