Digestive Enzymes Flashcards
Locations & Functions
Enzymes that break down carbohydrates:
Where is Amylase found?
Amylase is secreted by the pancreas into small intestines and salivary glands in the mouth.
Enzymes that break down carbohydrates:
What does Amylase do?
Amylase is responsible for the initial process of digestion of carbohydrates.
Enzymes that break down carbohydrates:
Where is Maltase found?
Maltase is synthesized by cells of the mucous membrane lining the intestinal wall.
Enzymes that break down carbohydrates:
What does Maltase do?
Maltase further breaks down carbohydrates, specifically the sugar, maltose, into glucose.
Enzymes that break down carbohydrates:
Where is Lactase found?
Lactase is produced by cells that line the walls of the small intestine.
Enzymes that break down carbohydrates:
What does Lactase do?
Lactase functions at the small intestine wall to break down lactose into smaller sugars called glucose and galactose.
Enzymes that break down carbohydrates:
Where is Sucrase found?
Sucrase is synthesized by the cells
that line the walls of the intestine.
Enzymes that break down carbohydrates:
What does Sucrase do?
The role of the sucrase is to break down sucrose into simple sugars, glucose and fructose.
Enzymes that break down proteins:
Where are Proteases found?
Proteases are found mainly in the
stomach and small intestines.
Enzymes that break down proteins:
What do Proteases do?
Proteases are enzymes that break down proteins into amino acids.
Enzymes that break down proteins:
Where is Trypsin found?
Trypsin is secreted from the walls of
the small intestine.
Enzymes that break down proteins:
What does Trypsin do?
Trypsin is used in the secondary step of protein digestion resulting in amino acids.
Enzymes that break down proteins:
Where is Pepsin found?
Pepsin is secreted by the stomach as pepsinogen and activated by the gastric acid to pepsin.
Enzymes that break down proteins:
What does Pepsin do?
Pepsin is used to digests proteins into smaller units called peptides.
Enzymes that break down fats:
Where are Lipases found?
Lipases are found in the small
intestine.
Enzymes that break down fats:
What do Lipases do?
Lipases are a group of fat-digesting enzymes found in the blood, gastric juices, pancreatic secretions, intestinal juices, and fat tissues.
Enzymes that break down fats:
Where is Lingual Lipase found?
Lingual lipase is an enzyme secreted in the mouth and is swallowed with food and saliva. It accumulates in the stomach between meals.
Enzymes that break down fats:
What does Lingual Lipase do?
Lingual lipases are a group of enzymes that breakdown dietary fats.
Enzymes that break down fats:
Where is Gastric Lipase found?
Gastric lipases are found in the upper part of the stomach.
Enzymes that break down fats:
What does Gastric Lipase do?
Gastric lipases are a group of enzymes which breakdown fats during digestion.
Enzymes that break down fats:
Where is Phospholipase found?
Phospholipases are found in the
small intestine.
Enzymes that break down fats:
What does Phospholipase do?
Phospholipases are enzymes that break down specific fats called phospholipids during digestion.
Enzymes that break down fats:
Where is Cholesterol Esterase found?
Cholesterol Esterase is found primarily in the pancreas but has been detected in other tissues as well.
Enzymes that break down fats:
What does Cholesterol Esterase do?
Cholesterol esterase breaks down specific fats into sterols and fatty acids, but required bile salts to complete this action.
Enzymes that break down fats:
Where are Nucleases found?
Nucleases are found in the small intestine.
Enzymes that break down fats:
What do Nucleases do?
Nucleases are enzymes that degrade nucleic acids, either DNA or RNA. They do this to repair damaged strands of DNA or RNA.
Enzymes that break down fats:
Where is Pancreatic Lipase found?
Pancreatic lipase is usually secreted by the pancreas and transferred to the duodenum of the small intestine.
Enzymes that break down fats:
What does Pancreatic Lipase do?
Pancreatic lipase breaks down fat, cholesterol esters, and fat-soluble vitamins.
