Name the products of lactose hydrolysis.

Glucose and galactose

9

Where is amylase made in the body?

Salivary glands and pancreas.

10

Where are disaccharidases found?

On the membranes of the epithelium cells lining the ileum.

Name the enzyme responsible for the hydrolysis of lipid.

Lipase

12

Where is lipase made?

Pancreas

13

Name three different types of protease.

Endopeptidase
Exopeptidase
Dipeptidase

14

Where are endopeptiadases made?

Stomach

15

Where are exopeptidases made?

Pancreas

16

Name the type of bond broken by amylase enzymes.

Glycosidic bond

17

Name the type of bond broken by lipase enzymes.

Ester bond.

18

Name the type of bond broken by protease enzymes

Peptide bond

19

Where are dipeptidases found?

On the membrane of the epithelium lining the small intestine

20

Where is bile made?

Liver

21

Where is bile stored?

Gall bladder

22

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.

23

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
