the protein in the human body found in the cells of the mucles
Cheese is mainly composed of lipids and proteins. Proteins are digested in the stomach and small intestines and absorbed in the small intestines. Lipids are emulsified by bile in the duodenum and absorbed later in the small intestines. The only thing in cheese that makes it to the large intestines is the moisture, but most cheeses do not have a large water content.
found below the stomach
Yes; the small intestine has carrier proteins for transport, as do all other cellular structures.
No, but the closest thing to it would be the Golgi apparatus. Cells make up the organ that is the intestines, so an organ (the intestines) cannot be found within a cell, but only an animal cell could be found in intestines.
proteins are found in meat.
Proteins could be found in milk, fish, or chicken.
Muscles
Yes, neurotransmitters are found wherever nerves are found.
Intestinal fluid can be found in the intestines, which is a part of the digestive system. It helps with the digestion and absorption of nutrients from food.
the small intestines
in proteins.
Surprisingly, membrane proteins are found in or attached to the membrane.
