The enzymes inside the mouth create an acidic environment. Stomach also secretes hydrochloric acid having a pH less than 7 creating an acidic environment. The pH of the gastric juices in the stomach is in the range of 2-5 which is slightly acidic in nature.

Question 15. The pH of the gastric juices released during digestion is : (a) less than 7 (b) more than 7 (c) equal to 7

The pH of the gastric juices released during digestion is : (a) less than 7 (b) more than 7 (c) equal to 7

Gastric juice, thin, strongly acidic (pH varying from 1 to 3), almost colorless liquid secreted by the glands in the lining of the stomach. Its essential constituents are the digestive enzymes pepsin and rennin, hydrochloric acid, and mucus.

The pH of gastric juice secreted by the oxyntic or parietal cells of the stomach is acidic in nature. It is acidic because the protein-digesting enzymes of the stomach such as pepsin do not work well in the basic medium so the pH is maintained between 1.5 to 3.5 in the stomach. Hence, the pH of gastric juice is 2.

The pH of the gastric juices released during digestion is : (a) less than 7 (b) more than 7 (c) ...

Enzymes present in gastric juice of human are as follows: (1) Pepsin: In the presence of HCl, it converts protein to peptones. (2) Renin: In the presence of HCl and Ca + + ion, it converts into calcium paracaseinate. (3) Gastric lipase: It converts fats into fatty acid and glycerol.

In the presence of peptides in the stomach, gastrin hormone is released into the bloodstream. This hormone stimulates the gastric glands to produce gastric juice. Gastric juice is an acid juice (pH 1 - 3). HCl (Hydrochloric Acid) keeps the stomach pH acidic. As HCl is a strong acid, it will kill most of the bacteria present in the food.

Choose the correct statements regarding the gastric juices. I. Pepsin converts proteins into peptones partially. II. Hydrochloric acid kills the germs present in food and regulates pH for digestion in the stomach. III. Mucus protects the stomach wall from the action of digestive juices.

The pH of the gastric juices released during digestion is: A. less than 7. B. more than 7. C. equal to 7 ...
