Solution

The correct option is A 6.8, 2, 8
A. 6.8, 2, 8
Solution: Optimal pH for the activity of the enzymes of salivary glands (e.g. ptylin) is around 7. Optimal pH for the activity of the enzymes of stomach (e.g. pepsin) is 1.5-2 . Optimal pH for the activity of the enzymes of small intestine (e.g. trypsin) is around 8.
So the correct answer is "6.8, 2, 8"
