Which of the following statements is true about protein digestion?
- Saliva does not contain proteolytic enzyme; protein digestion begins in the stomach by the action of pepsin. - Trypsinogen is conveed to trypsin by the action of enterokinase in duodenum. - Trypsin and chymotrypsin are endopeptidases; carboxypeptidase and aminopeptidase are exopeptidases. - Of the total protein digestion, 10%-20% occurs by the action of pepsin.
Protein digestion stas with the salivary action
Trypsinogen is conveed to trypsin by the action of bicarbonate in duodenum
Trypsin and chymotrypsin are exopeptidases
10%-20% protein digestion occurs by pepsin action in stomach.
