What is role of acid in our stomach?

Question

Answer

Digestion... may Be Proper n Improper

Answer

The hcl acid present in our stomach helps to breakdown food molecules which also creates an acidic medium....in which an enzyme name pepsin is formed.It also kills bacterias n micro org which entered in stomach with food

Answer

The role of HCl in our stomach are as follows:1-It kills the bacteria which may enter in our Stomach with the food2-It makes the medium of food acidic so that the enzyme pepsin can work on it.HOPE HELP U.

Answer

HCl in stomach acts as a barrier against microorganisms to prevent infections and is important for the digestion of food. Its low pH denatures proteins and thereby makes them susceptible to degradation by digestive enzymes such as pepsin. The low pH also activates the enzyme precursor pepsinogen into the active enzyme pepsin by self-cleavage.

Answer

Role of hcl is to activate pepsin, helps to digest food,and kill the germs

Answer

Activation of prorenin to renin and pepsinogen to pepsin. To kill the germs inside the stomach. It helps in digestion of food.

Answer

HYDROCHLORIC ACID is secreted by the parietal cells present in stomach and it serves the following functions,,,: ... Hydrochloric acid also activates pepsin, via its conversion from a substance called pepsinogen,,,. The function of Pepsin is to mainly digest the protein we eat...

Answer

HCL acid helps to digest food and it kills the bacteria which is entered  by food in the stomach...

Answer

Acid in our stomach plays an essentialrole in the immune system by killing harmful bacteria and parasites that are ingested with food. Stomach acidactivates the enzyme pepsin needed for protein digestion. Stomach acidsignals to the pancreas produce digestive juices and enzymes to further break down food.

Answer

HCL is an acid which is present in our stomach and kills the germs present in the stomach. It also helps in the digestion of protein by enzyme pepsin which can only work in an acidic medium.

Answer

The Role of Acid in our Stomach

The stomach plays a crucial role in the digestion of food, and one of its key components is stomach acid. Stomach acid, also known as gastric acid, is a digestive fluid produced by the gastric glands located in the lining of the stomach. It consists mainly of hydrochloric acid (HCl) and other enzymes and chemicals necessary for the digestion process. The acid in our stomach serves several important functions.

Digestion of Proteins

One of the primary roles of stomach acid is to aid in the digestion of proteins. Acidic conditions in the stomach activate an enzyme called pepsinogen, which is secreted by the chief cells in the gastric glands. Pepsinogen is converted into its active form, pepsin, when it comes into contact with the acidic environment. Pepsin is responsible for breaking down proteins into smaller peptides, which can then be further digested by other enzymes in the small intestine.

Activation of Enzymes

Stomach acid also plays a crucial role in activating other digestive enzymes. For example, it activates gastric lipase, an enzyme that aids in the digestion of fats. Additionally, the acid helps to activate intrinsic factor, a protein necessary for the absorption of vitamin B12 in the small intestine. Without sufficient stomach acid, these enzymes may not function properly, leading to incomplete digestion and nutrient deficiencies.

Killing Microorganisms

Another important function of stomach acid is to kill harmful microorganisms that may be present in the food we consume. The highly acidic environment of the stomach provides a hostile environment for many bacteria, viruses, and parasites. This helps to prevent infections and foodborne illnesses. However, it is worth noting that some bacteria, such as Helicobacter pylori, have adapted to survive in the acidic conditions of the stomach, leading to conditions like gastritis and peptic ulcers.

Maintaining pH Balance

The stomach acid also plays a role in maintaining the pH balance within the digestive system. It helps to keep the pH levels in the stomach highly acidic (around 1.5-3.5), which is necessary for optimal digestion. This acidic environment is needed for the activation of enzymes, as mentioned earlier, and also aids in the absorption of certain nutrients like iron and calcium.

In conclusion, stomach acid plays a vital role in the digestion process. It helps break down proteins, activates enzymes, kills harmful microorganisms, and maintains the pH balance necessary for optimal digestion and nutrient absorption. However, it is important to note that excessive production of stomach acid can lead to conditions like gastroesophageal reflux disease (GERD) and stomach ulcers, highlighting the importance of maintaining a healthy balance of stomach acid.
