Question

1. How can you say that the carbohydrates are not completely digested until they reach
intestine?(ASI)​

Answer 1

Explanation:

The starch is digested in mouth by chewing and the action of the amylase. Amylase works in the pH of 6.8. whereas the pH in stomach is 2. Amylase cannot work under such pH and there is no other enzyme to digest starch in the stomach, except pepsin and rennin, that are concerned with protein digestion.
