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.
The optimum pH for stomach protease, specifically pepsin, is around 1.5 to 2. It functions best in the highly acidic environment of the stomach, which helps to break down proteins efficiently for digestion.
The optimal pH for pepsin, an enzyme found in the stomach that helps in protein digestion, is around 2.0. This low pH is necessary for pepsin to be active and function effectively in breaking down proteins into smaller peptides.
The optimum pH is neutral, 7.
The optimum pH of lactase is pH = 6.5.
Pepsin secreted in the stomach, works at highly acidic pH and the pH could be as low as 2. The optimal pH for pepsin is thus near about 2. This pH is maintained by HCl secreted by the gastric glands in the stomach.
Pepsin is therefore acidic since the pH in the stomach is 2

Hydochloric acid is produced in the stomach to a) kill pathogens in our food b) gives optimum pH for enzymes to work in
The optimum pH is neutral, 7.
pepsin is found in the stomach and the pH there is 2 while trypsin is found in the small intestine (duodenum and jejunum) and the pH there is 8-9. Thus, the optimum pH levels for pepsin and trypsin are 2 and 8-9 respectively.
The optimum pH of lactase is pH = 6.5.
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
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.

To determine the optimum pH of an enzyme, you can conduct experiments at different pH levels and measure the enzyme activity. The pH at which the enzyme shows the highest activity is considered its optimum pH.
