Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Pancreatic amylase converts starch to maltose and pancreatic lipase break down fat into fatty acids and glycerol (Grabowski et al, 2000: page 841). Raven, New York, pp 883 3 Gastric juice is a general term that includes the fluid secreted from the cardiac, oxyntic and pyloric glands, all of which secrete distinctly different fluids.

The gastric juice comprises about 0.5% of solid matter including sodium chloride with traces of potassium chloride and phosphates, mucin and enzymes pepsin, rennin and gastric lipase, hydrochloric acid and mucin. Acidity of gastric juice: 40-60 mEq/liter v. […] HCl - it kills the germs present in the food and makes the food medium acidic which is essential for the action of pepin. The Biological Function of Gastric Juice.Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. ADVERTISEMENTS: In this article we will discuss about the composition and enzymes of gastric juice. Gastric Juice releases Dilute Hydrochloric Acid, Pepsin and Mucus which helps in the digestion . 2. its also explained in class 10 science chapter 6 life process here is your answer please mark me as brainliest ForeverSweety26 ForeverSweety26 Answer: Hi..!! Rennin: A proteolytic enzyme found in gastric juice of infants which helps in the digestion of milk proteins. PEPSIN- It helps in digestion of protein present in food. This gastric acid, or colloquially known as gastric “juice,” will work to break down the bonds within the food particles at the molecular level. The pH of the gastric juice is 1.5 to 2.5. The gastric juice in our stomach contains enough HCl to make the hydrogen ion concentration about 0.10 mole litre. ('95') II3, 4I9-424 THECOMPOSITION OF GASTRIC JUICE ByJ. Although it does not contain any digestive enzymes, it plays an important role in the digestion of fats. The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Functions of mucus: The major function of mucus is usually to coat the passageways of the nose area, throat, sinuses, lungs as well as digestive system and have them from getting dry off. It is mainly made up of electrolytes, mucus, enzymes, hydrochloric acid, intrinsic factor etc. Let us discuss the Gastric Glands. 2.HCL: (a).It makes the medium acidic for the secretion of pepsin. Bile is a digestive juice secreted by the liver. (b).it also kills the microbes present in food. It is acidic in nature due to the presence of HCl. Class 10 Science Chapter 6 Important Questions of Life Processes updated for new academic session 2021-22 based on new NCERT Textbooks and following the latest CBSE Curriculum for session 2021-2022.

Pepsin works best at the acidity of normal gastric juice, which has the pH that ranges between 1.5 and 2.5. gastric juice Fluid comprising a mixture of substances, including pepsin and hydrochloric acid, secreted by glands of the stomach. Renin: It is an enzyme releasing from JGA, … What are the two vital function of human kidney? Presence of hydrochloric acid in gastric acid produced by the stomach prevents anemia, osteoporosis, nerve disorders, yeast infections, hair loss in women and many more illnesses. It must be noted that the reaction for the conversion of pepsinogen into pepsin requires a pH value of less than 5. Pepsin 79) During the cephalic phase of gastric secretion, A) the stomach responds to distention. Gastric juices are secreted from glands lining the stomach and function to break down food in the stomach and kill bacteria, according to the resource website About.com. Bile juice has bile pigments such as bilirubin and biliverdin. Answer: Translocation of If the answer is not available please wait for a while ii. This buffers acidic gastric juice in chyme, stops the action of pepsin from the stomach and creates pH for the digestive enzymes in the small intestines (Grabowski et al, 2000: page 840). The gastric gland is the primary secretory unit of the stomach. It contains about 99. The gastric gland is an essential body component because it secretes gastric juice. Write three functions of gastric juice. Gastric juice have three chemical substance HCL Pepsine and mucus. Pepsin enzyme will have the unique role of breaking the strong peptide bonds that hold the Its principal function is to … D) the intestinal reflex inhibits gastric emptying. Human digestive system - Human digestive system - Gastric secretion: The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. 4 percent water and the rest of the portion includes inorganic and organic solids. It contains water, salts, mucin, hydrochloric acid, pepsin, rennin and gastric lipase. Gastric glands secrete HCL, pepsinogen, mucous.Gastric juice is a secretion of gastric glands located in the lining of the stomach. Night secretion (during sleep) alone is 400 ml/day. It has been estimated that on an average about two to three litres of gastric juice is secreted per HCl Pepsine digest protein.
