Protein digestion happens alot in the stomach

In summary, protein digestion is the process of breaking down proteins into smaller molecules called amino acids, which can be absorbed and used by the body. This primarily occurs in the stomach and small intestine, where enzymes such as pepsin, trypsin, and chymotrypsin break down proteins into peptides and individual amino acids. The highly acidic environment in the stomach is essential for the activation of pepsin and denaturing proteins, making them easier to digest. Once digested, amino acids are absorbed into the bloodstream and used for various functions in the body.

Okay so protein digestion happens a lot in the stomach...how come the stomach doesn't just digest itself??

SAme with in the cell walls the stomach produces pepioinogen...so what does protien digestion do in that area.
and how come the cells don't digest themselves

The stomach is protected by excreted proteins that line the stomach, I'd have to look up the details.

yea that's the mucus...it protects the enzymes digesting the walls of the stomach
 

1. What is protein digestion?

Protein digestion is the process by which proteins are broken down into smaller molecules called amino acids, which can then be absorbed and used by the body for various functions.

2. Where does protein digestion primarily occur?

Protein digestion primarily occurs in the stomach and small intestine.

3. How does protein digestion happen in the stomach?

In the stomach, protein digestion is initiated by the enzyme pepsin, which breaks down large protein molecules into smaller peptides.

4. Why does protein digestion happen a lot in the stomach?

The stomach is a highly acidic environment, with a pH of 1.5-3.5, which is necessary for the activation of pepsin. This acidic environment also helps to denature proteins, making them easier to digest.

5. What happens to proteins after they are digested in the stomach?

Once proteins are broken down into smaller peptides in the stomach, they are further digested in the small intestine by enzymes such as trypsin and chymotrypsin. These enzymes break the peptides down into individual amino acids, which can then be absorbed into the bloodstream and used by the body for energy and building tissues.
