The small intestine produces and secretes many enzymes, as it is here where digestion mainly occurs. These enzymes include:
The enzymes mentioned above are actually produced by the pancreas.
In the small intestine - After being in the stomach, food enters the duodenum, the first part of the small intestine. It then enters the jejunum and then the ileum (the final part of the small intestine). In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food.

Carbohydrase enzymes are produced in the salivary glands and in the pancreas. These enzymes help break down carbohydrates into simpler sugars for absorption in the small intestine.
Enzymes in the small intestine can break larger molecules such as proteins into smaller molecules such as amino acids. These enzymes are either produced in the pancreas and taken to the first part of the small intestine by the pancreatic duct or some enzymes may be produced by the lining of the small intestine called the "brush border" in the first part of the small intestine. Large molecules such as proteins or starch need to be broken down to smaller molecules before they can be absorbed into the bloodstream and beusableto the person's body cells.
The bile produced in the liver eats the fats in the food and the enzymes produced in the pancreas breaks down the fats before the the bile eats it because the enzymes break down the fats in to smaller particlesIt helps neutralize the stomach acid so it wont burn it.as part of the digestive system, the pancreas produces enzymes that flow into the small intestine and help break down starches, proteins, and fats.
Enzymes produced in the pancreas are secreted into the small intestine through the pancreatic duct. When food enters the small intestine from the stomach, these enzymes mix with the food as it is digested. This allows the enzymes to break down carbohydrates, proteins, and fats, facilitating nutrient absorption. Thus, even though food doesn't pass through the pancreas, the enzymes reach it effectively in the small intestine.

The stomach contains enzymes that break down protein.
Most digestive enzymes are produced in the stomach. You will find that with the complex ducts throughout the human body these enzymes can travel to other areas of the digestive system. These areas include the salivary glands, the stomach, the pancreas, and the intestines.
Disaccharidases are produced in the brush border of the small intestine, specifically in the microvilli of the enterocytes lining the small intestine. These enzymes are involved in breaking down disaccharides into monosaccharides to facilitate their absorption in the digestive system.
Nucleases are produced in the pancreas. These are enzymes that digest nucleic acids, and the word nuclease represents any nucleic acid breaker.
In frogs, digestive enzymes are produced in the pancreas and secreted into the small intestine through the pancreatic duct. As food enters the stomach, it is partially digested and then passed into the small intestine, where the enzymes mix with the chyme to aid in further digestion. Additionally, bile from the liver also contributes to the digestive process in the small intestine. This coordinated action ensures efficient breakdown of food for nutrient absorption.
