19. And 20. Please answer these
Dear student,
19.
The ptyalin enzyme is another name for salivary amylase. It is produced by salivary glands in the mouth. About 30% of the carbohydrate is hydrolyzed into disaccharides like maltose by this enzyme.
Therefore, the correct option is D.
20.
Chemical digestion of protein begins in the stomach, where the proenzyme pepsinogen is released, which is then transformed into the active enzyme pepsin when exposed to hydrochloric acid. It's a protease that breaks down proteins into proteases and peptones.
Thus, the correct option is B.
