Explanation / Answer

False statements:

A)Mechanical digestion only occurs during the active chewing.

Mechanical digestion occur in mouth as well as in stomach. It involves mastication- chewing of food, and churning. The food chewed at the mouth move through oesophagus into small intestine by peristalsis movements and muscle churn the food into small pieces.

B)Salivary amylase operate best at pH of 2.0

The pH of salivary amylase is 6.7-7.0. At this pH salivary amylase hydolysis alpha 1,4- glycosidic linkages in amylopectin, amylose and glycogen in stomach.

C)All protein digestion occurs in the stomach.

Protein digestion occur in stomach by gastic juice(HCl), rennin, pepsin, gelatinase.and in small intestine by proteolytic enzymes such as trypsin, chymotrypsin. elastase, carboxypeptidase, aminopeptidase, carboxypeptiase,and dipeptisase.
