Digestion Flashcards
Name the type of reaction used to digest large biological molecules.
Hydrolysis
Name the products made when starch is digested.
Maltose -> (alpha) glucose
Name the products made when lipids are digested.
Fatty acids and monoglycerides
Name the products made when proteins are digested.
Amino acids
Name the enzyme used to hydrolyse starch.
Amylase
Name the enzyme used to hydrolyse maltose.
Maltase
Name the monosaccharides produced when sucrose is hydrolysed.
Glucose and fructose
Name the products of lactose hydrolysis.
Glucose and galactose
Where is amylase made in the body?
Salivary glands and pancreas.
Where are disaccharidases found?
On the membranes of the epithelium cells lining the ileum.
Name the enzyme responsible for the hydrolysis of lipid.
Lipase
Where is lipase made?
Pancreas
Name three different types of protease.
Endopeptidase
Exopeptidase
Dipeptidase
Where are endopeptiadases made?
Stomach
Where are exopeptidases made?
Pancreas
Name the type of bond broken by amylase enzymes.
Glycosidic bond
Name the type of bond broken by lipase enzymes.
Ester bond.
Name the type of bond broken by protease enzymes
Peptide bond
Where are dipeptidases found?
On the membrane of the epithelium lining the small intestine
Where is bile made?
Liver
Where is bile stored?
Gall bladder
Explain how bile increases the rate of lipid digestion.
Emulsifies lipids.
Increases the surface area of lipid for lipase to act on.
Breaks lipid globules up into smaller globules.
Describe how glucose is transported into the blood.
Sodium ions actively transported out of epithelium cell.
Using sodium/potassium pump
Maintains a low concentration of sodium ions inside epithelium cell.
Sodium ion and glucose co-transported from small intestine into epithelial cell down the concentration gradient for sodium ions.
Glucose the passes into blood by facilitated diffusion
