Question

Salivary amylase is stimulated by

• A. $K^{+}$
• B. $N^{+}$
• C. $HC{O}_3^{-}$
• D. $C{l}^{-}$

Answer 1

The correct option is D $C{l}^{-}$

Salivary amylase is secreted by the salivary glands in the mouth. This enzyme is involved in partial digestion of carbohydrates. The carbohydrates in food are broken down to maltose. Maltose is further digested into glucose in the small intestine. The chloride ion is involved in the allosteric activation of salivary amylases by binding at the allosteric site of amylase. Thus the correct answer is option D.
