Within the stomach, there are three different substance that help in digestion. Salivary amylase enters the stomach from salivary ducts in the mouth which helps break down sugars like starch. Pepsin is an enzyme that aids in the breakdown of proteins and is secreted through glands within the stomach. Hydrochloric acid is also secreted by the stomach and the main function of that is to kill harmful bacteria within the stomach. The main digestion happens in the small intestine when the chyme enters the duodenum and sodium bicarbonate is added by the pancreas.

∙ 15y agoAll kinds of chemical reactions occur with HCl in the stomach. You already know that HCl is hydrochloric acid, and the chlorine ion (Cl-) would love to "dump" its hydrogen (H) "partner" and bond with something else. It (the chlorine ion) will "tag" just about any metal. And because many, many things we eat contain compounds have that metal atom in their molecules, the Cl- will take apart other molecules to selectively bind with something (like a metal atom) in there that it "likes" better than hydrogen. This is the essence of why and how hydrochloric acid breaks down foodstuffs. Remember that all of this happens in a "soup" or solution of many materials in the stomach. Frankly, it's a chemical mess, but the chlorine ion knows what it wants, and will "find" it and take apart whatever it has to to bind with something it likes.

Where in humans does most chemical digestion occurs?
most chemical digestion occurs in the duodenum
A coiled tube in which chemical digestion occurs?
The small intestine is a coiled tube in which chemical digestion occurs.
What is the name of the organ in the digestive system where the chemical breakdown of food primarily occurs?
Some chemical digestion of carbohydrates occurs in the mouth with salivary amylase. Most chemical digestion occurs in the duodenum of the small intestine.
Are the intestines a physical or chemical change?
Digestion that occurs in the intestines is a chemical change.
What chemical speeds up the chemical reaction in digestion?
Hydrochloric acid

A coiled tube in which chemical digestion occurs?
The small intestine is a coiled tube in which chemical digestion occurs.
Most chemical digestion occurs in which intestine?
Majority of digestion occurs in the small intestine.
What is the name of the organ in the digestive system where the chemical breakdown of food primarily occurs?
Some chemical digestion of carbohydrates occurs in the mouth with salivary amylase. Most chemical digestion occurs in the duodenum of the small intestine.
When protein compounds are catalyzed what do they do to the chemical reaction during digestion?
Neutralize chemical reactions during digestion
When a chemical reaction occurs atoms are never?
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
Are the intestines a physical or chemical change?
Digestion that occurs in the intestines is a chemical change.
Are intestines a chemical or physical change?
Digestion that occurs in the intestines is a chemical change.
Does the small intestine have mechanical or chemical digestion?
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
What chemical speeds up the chemical reaction in digestion?
Hydrochloric acid
The largest amount of chemical digestion occurs in your what?
Most chemical digestion takes place in the duodenum (the first part of the small intestine).
Most chemical digestion occurs here?
The small intestine
