They don't. The pH of the stomach may vary with time, but it's basically the same throughout. Perhaps you are thinking of the digestive system as a whole? The stomach is acidic, but the small intestines is alkaline and the large intestine is neutral or slightly acidic. The main reason for the variation is to allow the different enzymes to work well.

∙ 15y agoThe best pH would be between pH 1,8 and 4,4 , since the pepsin, an enzyme in the stomach works effectively under this pH range.

What is the pH for pepsin?
Pepsin is a type of protease that works mainly in the stomach. As a result, its optimum pH is around 2. The high acidity is provided by the hydrochloric acid in the stomach.
What is the optimum pH for stomach protease?
Pepsin is an enzyme that catalyzes the breakdown of proteins int peptides. Its optimum pH range is between 1 to 4.
What is the pH optimum of alpha amylase?
The optimum pH is neutral, 7.
What is the optimum PH of lactase catalyzed reaction?
The optimum pH of lactase is pH = 6.5.
Lipase optimum pH?
A lipase is an enzyme that catalyzes the breakdown of fats. Its optimum pH varies depending on the type of lipase. Pancreatic lipase has an optimum pH of 8.0 while stomach lipase ranges from 4.0 to 5.0.
What is the pH for pepsin?
Pepsin is a type of protease that works mainly in the stomach. As a result, its optimum pH is around 2. The high acidity is provided by the hydrochloric acid in the stomach.
During digestion the pH in the stomach is 2 What does this indicate about the optimum pH of pepsin?
Pepsin is therefore acidic since the pH in the stomach is 2
What is the optimum pH for stomach protease?
Pepsin is an enzyme that catalyzes the breakdown of proteins int peptides. Its optimum pH range is between 1 to 4.
At what pH would the enzyme be most effective?
It depends on what type of Enzyme. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an optimum pH of 5.6.
Optimum pH level for enzymes?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
What is the optimum pH of elastases?
The optimum pH is 8.8
What is the acid secreated by the stomach?
Hydochloric acid is produced in the stomach to a) kill pathogens in our food b) gives optimum pH for enzymes to work in
What is the pH optimum of alpha amylase?
The optimum pH is neutral, 7.
What is the optimum PH of lactase catalyzed reaction?
The optimum pH of lactase is pH = 6.5.
What effect would a higher pH have on the temperatures optimum for invertase?
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
Lipase optimum pH?
A lipase is an enzyme that catalyzes the breakdown of fats. Its optimum pH varies depending on the type of lipase. Pancreatic lipase has an optimum pH of 8.0 while stomach lipase ranges from 4.0 to 5.0.
Does the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach?
The optimum pH for tryspin is about 8.0, which is the pH of the intestine, whereas the pH of gastric juice is 1.5-2.0, which is highly acidic.
