Secretions related to digestion
| Question | Answer |
|---|---|
| What enzyme do they salivary glands produce? What is the function of this enzyme? How much is produced in a day? | salivary amylase (ptyalin), starts the break down of starch, 1,000 – 1,500 mL/day |
| Name four secretions/enzymes produced in the stomach. | Pepsinogen, HCL acid, Lipase, Intrinsic factor |
| What is the function of pepsinogen? | protein digestion |
| What is the function of HCL acid? | Activation of pepsinogen to pepsin |
| What is the function of Lipase? | Fat digestion |
| What stomach secretion is essential for the absorption of cobalamin in the ileum? | Intrinsic factor |
| About how much juice is produced by the stomach in a day? | 2,500mLs |
| Name the enzymes of the small intestine (8). | Enterokinase, Amylase, Peptidase, Aminopeptidase, Maltase, Sucrase, Lactase, Lipase |
| Acitvation of typsinogen to trypsin | Enterokinase |
| Carbohydarte digestion | Amylase |
| Protein digestion | Peptidase and aminopeptidase |
| Maltose to 2 glucose molecules | Maltase |
| Sucrose to Glucose and fructose | Sucrase |
| Lactose to Glucose of galactose | Lactase |
| End products of Maltose | 2 glucose molecules |
| End products of sucrose | glucose and fructose |
| End products of lactose | glucose and galactose |
| Name 4 pancreatic secretions related to digestion. | Trypsinogen, Chymotrypsin, Amylase, Lipase |
| Function of typsinogen | Protein digestion |
| Function of Chymotrypsin | protein digestion |
| Pancreatic secretion that turns starches into disaccharides | amylase |
| Pancreatic enzyme for fat digestion | Lipase |
| Organs that produce bile | Liver and gallbladder |
| Function of bile | emulsification of fats and aids in absorption of fatty acids and fat-soluable vitamins |

| What is the daily amount of digestive secretions from the small intestine? | 3,000 mL |
| 700mL | the amount of secretions for digestion produced by the pancreas in a day |
| 1,000mL | the amount of secretions for digestion produced by the liver and gallbladder each day |
| Hydrolyzes starches to maltose | Ptyalin - salivary amylase |
