During digestion the pH in stomach is 2 What does this indicate about optimum of pepsin?

The optimum pH of pepsin is 1.5 to 2.0. This means that pepsin works best in a highly acidic environment. The stomach is able to maintain this acidic environment through the production of hydrochloric acid. Hydrochloric acid also helps to break down food and kill bacteria.

Pepsin is an enzyme that is produced in the stomach. It is responsible for breaking down proteins into smaller peptides. Pepsin is most active in the acidic environment of the stomach. The pH of the stomach is typically between 1 and 2. This is why pepsin is able to work so effectively in the stomach.

If the pH of the stomach were to become too high, pepsin would not be able to function properly. This could lead to a condition called hypochlorhydria, which is a condition in which the stomach does not produce enough hydrochloric acid. Hypochlorhydria can lead to a number of problems, including indigestion, malabsorption, and bacterial overgrowth.
