Where is amylase released

Answer 7

Small intestines

Question 8

Where are membrane bound disaccharidase

Answer 8

Plasma membrane of epithelial cells in ileum

Question 9

Why are membrane bound enzymes useful

Answer 9

Short diffusion pathway

High conc directly outside for quick diffusion down conc grad

Question 10

Answer 10

Ester

Question 11

What bonds are broken in the hydrolysis of polysaccharides

Answer 11

Glycosidic

Question 12

What do lipids break down into

Answer 12

Monoglyceride + fatty acids

Question 13

Where are lipase made

Answer 13

Pancreas

Question 14

Where do lipase get released

Answer 14

Small intestine

Question 15

Where are bile salts produced

Answer 15

Liver

Question 16

Why is lipid emulsified

Answer 16

Increase SA for lipase to work on

Question 17

What is a micelle

Answer 17

Monoglycerides and fatty acids stuck together with bile salts

Question 18

What bond to endopeptideases work on

Answer 18

Peptide bonds within the polypeptide chain

Question 19

Where do exopeptideases break bonds

Answer 19

The end peptide bond of the polypeptide chain. Releasing 1 amino acid

Question 20

Why are endo and exo peptidase used

Answer 20

Increase SA for dipeptideases to work on

Question 21

How is glucose moved into the ileum

Answer 21

Active transport on a co transport protein with N’a+

Question 22

How is galactose moved into the ileum

Answer 22

Active transport on co transport protein with N’a+

Question 23

How is fructose moved into the ileum

Answer 23

Facilitated diffusion

Question 24

How do micelles help monoglycerides and fatty acids be absorbed into the ileum

Answer 24

Micelles constantly break up and release the monoglycerides and fatty acids allowing them to be absorbed. Monoglycerides and fatty acids are lipid soluble so can diffused straight across the phospholipid bilayer

Question 25

Can whole micelles be absorbed My the plasma membrane

Answer 25

No

Question 26

How are amino acids transported into the ileum

Answer 26

Na co transporter protein
