Absorption And Starch Digestion Flashcards
What are absorbed by the small intestine by simple diffusion?
Lipids and other hydrophobic molecules
What are absorbed by the small intestine by facilitated diffusion?
Fructose and other hydrophilic molecules
What are absorbed by active transport?
Glucose, amino acids, Na, Ca, and Fe ions
What is absorbed through pinocytosis?
Fat droplets in the lumen of the small intestine
What is pinocytosis?
the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane
What are the two occurrences of starch?
Amylose and amylopectin
What is the difference between amylose and amylopectin?
Amylopectin is branched while amylose is unbranched
What is the optimal pH for amylase activity?
~7
What are the only type of bonds amylase can break down?
A-1, 4 glycosidic bonds
What is amylopectin digested into?
Dextrins
Where can maltase be found in the small intestine?
The epithelial lining
What is the product of hydrolysed glucose?
Glycogen
