Enzyme or Substance Source of Enzyme or Substance Salivary amylase Salivary glands Gastrin G cells in the stomach Pepsin HCL Gastric chief cells Parietal cells in the stomach CKP Enteroendocrine cells in the duodenum Secretin Krypts of the small intestine Small intestinal enzymes Enterokinase Trypsinogen/trypsin Pancreas Duodenum Pancreas Chymotrypsinogen/chymotrypsin Carboxypepidase Pancreas Pancreas Sodium bicarbonate Bile Pancreas Liver Pancreatic enzymes Pancreas Function of Enzyme or Control Substance Catalyzes hydrolysis of starch The thought of food into sugars Enhances churning and causes the Bolus entering (the mucosa release of HCL and pepsinogen distends and the rugae flattens) Breaks down proteins HCL Aids in digestion of proteins, Gastrin activates pepsin Controls the release of digestive Presence of food enzymes from the krypts (SI) and pancreas as well as bile from the liver Causes sodium bicarbonate salts The entering of acid chyme to be released from the pancreas Aid in absorption of nutrients The presense of food Activates trypsinogen Activates procarboxylpeptidase Membrane bound enteropeptidase and chymotrypsinogen Act on chyme Trypsin Speeds up the hydrolysis reaction Trypsin of a protein into an amino acid The decrease in acidity of chyme Secretin Breaks down fat into smaller fat CKK causes the sphincter of Oddi goblets to allow lipases to better to ease which allows the bile to act on the fat be released into the duodenum Presence of food Help break down food and absorbtion of nutrients
