Question

In which organ of the digestive tract does hydrolysis of starch into maltose take place?

• A. Stomach
• B. Liver
• C. Mouth
• D. Duodenum

Hint:

Starch digestion starts in the \textbf{mouth} due to the action of \textbf{salivary amylase}.

Answer 1

The Correct Option is C

Step 1: Digestion of carbohydrates begins in the mouth.
Step 2: Saliva contains the enzyme salivary amylase (ptyalin).
Step 3: Salivary amylase hydrolyses starch into maltose and dextrins.
Step 4: In the stomach, acidic pH inactivates salivary amylase, so no further starch digestion occurs there.
