(18 cards)
What is digestion?
The process in which large molecules are hydrolysed by enzymes to produce small molecules that can be absorbed and assimilated.
What is the result of hydrolysis of carbohydrates?
Monosaccharides.
Where does the digestion of carbohydrates begin?
In the mouth.
What organ is involved in the digestion of carbohydrates in the mouth?
Salivary gland
What enzyme does the salivary gland produce?
Salivary amylase
What is produced when starch is hydrolysed?
Maltose
What increases the surface area for hydrolysis?
Chewing
Where does the rest of carbohydrate digestion occur?
Small intestine
What does the pancreas produce and release into the small intestine?
Pancreatic juice
What is pancreatic juice?
An alkaline fluid
What does pancreatic juice contain?
Pancreatic amylase
What does pancreatic amylase hydrolyse?
The remaining starch into maltose
Where does the complete hydrolysis of starch take place?
The ileum
What is the enzyme that hydrolyses maltose?
Maltase
What do maltase and other disaccharides form a part of?
The cell membrane of epithelial cells lining the ileum called membrane-bound disaccharides
What does maltase hydrolyse?
Maltose into two alpha glucose molecules
What does lactase hydrolyse?
