Question

what are the role of acid in your stomach and saliva in your mouth?????

Answer 1

*****The role Of HCl in stomach is :
1.. it converts inactive enzymes(zymogens) into active enzymes
Pepsinogen --------> pepsin(in presence of HCl)

prorennin-----------> rennin(in presence of HCl)

2. .It destroys all the bacteria present in food

3. HCl stops the action of saliva on food

4. It dissolves the hard protein of the food and makes it soft

--------------------------------------
******Function of saliva in mouth

1. It contains digestive enzyme salivary amylase (ptyalin) which helps in Digestion of starch

2. it contains lysozyme and thiocyantes which kill bacteria and also check growth of bacteria in Bucci pharyngeal cavity

3. it also contains IgA antibodies

Answer 2

Answer:

Hydrochloric acid plays a major role in the process of digestion. It creates a medium of gastric juice acidic so that the enzyme pepsin digests the protein and kills the bacteria present in them. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates the process of digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.

When there is no hydrochloric acid in the stomach, the iron absorption process is hindered as iron is essential in the solution for absorption. The stomach is prompted to produce acid when food is consumed for the production of the gastrin hormone. Hence, the acid lowers the pH level in the stomach, switching off the gastrin production which otherwise would lead to hypergastrinemia.
