Proteins are digested in your stomach. Pepsinogen is secreted by the chief cells. Pepsinogen is converted to pepsin by hydrochloric acid. This pepsin brakes the peptide bond of proteins to form polypeptides.

How do digested nutrients get in the blood stream?
After food get digested, there are enzymes that break down larger molecules such as proteins and carbohydrates into smaller molecules before it can pass into the blood stream. Mainly in the small intestine, nutrients pass into the blood stream. Depending on the type of "nutrient" that get passed through, some just diffuse through by difference in concentration gradient. Some require active pumps in the lining of the small intestine to pump the "nutrient" into the cell or blood stream. Hope I didn't confuse you too much. In short, some molecule just pass through. Some needs to be pumped across the cell membrane.
Does colon cancer occur most often in the large or small intestines?
Colon cancer is a type of cancer that occurs in the large intestine (colon), which is the final part of the digestive tract12. The large intestine is about 5 feet long and absorbs water and salt from the food that passes through it. The small intestine, also called the small bowel, is a long tube that connects the stomach and the large intestine. It is about 20 feet long and is responsible for digesting and absorbing nutrients from the food that enters it. Cancer of the small intestine is much less common than cancer of the large intestine. There are different types of small bowel cancer, such as adenocarcinoma, neuroendocrine tumors, lymphoma, and sarcoma. Therefore, colon cancer occurs most often in the large intestine, not the small intestine.
How does the structure of the small intestine improve its nutrient absorption?
1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem. 2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream. 3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently. 4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!
What organ uses Chemical digestion and absorption of food?
Chemical digestion occurs in the mouth and (mainly) in the stomach. The small intestine is where a majority of absorption occurs, the large intestine mainly absorbs water. Actually only protein is digested in the stomach the majority of the rest is digested in the small intestine. Some starch is digested by salivary amylase in the mouth the rest is digested by pancreatic amylase in the duodenum/jejynum. The protein is digested entirely in the stomach as this is the only area with a pH low enough for the action of pepsin. Fats are digests using secretions of the gall bladder in the dudodenum/jejunum.
What type of digestion occurs in the gallbladder?
No digestion occurs in the gallbladder, but the gall bladder can produce a greenish liquid called gall/bile, and that gall/bile flows into your small intestine to help digest food there. To be more specific, bile salts aid in the digestion of fats in the small intestine.
What type of food passes into the large intestine?
By the end of the small intestine, the nutrients have been digested from the food. What remains is waste. The large intestine absorbs excess water and a few vitamins from this waste, and then passes it out of the body via the rectum.
Which type of lipoprotein transports newly digested fat from the intestine through the lymph and blood?
Chylomicron
What type of digestion action does the small intestine have?
The small intestine is a water recovery system. Earlier stages of digestion use a lot of water, and then the water is reabsorbed in the small intestine.
What are intestines?
digest food

What type of tissue lines the peritoneal cavity of the small intestine?
The visceral peritoneum, a serious membrane, lines the outside of the small intestine where it meets the peritoneal cavity.
What is the type of digestion that breaks down food into molecules that can be absorbed?
small intestine
How does the length of the small intestine differ in various animals?
The length of small intestine depends upon type of mode of nutrition. carnivores have smaller and herbivores and omnivores have longer. they have hair-like projections called villi which increases the size of the intestine.
Major food digested in the stomach?
Food and liquids are digested from the mouth to the small intestine, including the stomach. Solid waste material is collected in the large intestine and passed through the colon out of the body.
One type of digestive liquid that is added in the small intestine is called?
Bile is added by the liver.
