6.10 Digestion Of Protein Cabs And Fats

Question 1

What are the 3 enzymes called for proteins and what do they do?

Answer 1

Endopeptidase- hydrolysis peptide bonds in the middle of the protein
Dipeptidase- hydrolyses peptide bonds to make single amino acids
Exopeptidase- Hydrolyses peptide bonds on the outside of the cell

Question 2

What are the 2 types of digestion?

Answer 2

Chemical
Physical

Question 3

What enzymes turn starch to glucose?

Answer 3

Amalayse
Maltase

Question 4

Where is maltase in the small intestine?

Answer 4

Bound to the membrane

Question 5

What is the order in which carbs are digested?

Answer 5

Amalayse breaks down starch in the moth
Goes to the stomach and denatures
Absorbed b co transport and carrier proteins in the ileum

Question 6

What do triglycerides turn into when hydrolysed?

Answer 6

A monoglyceride
2 fatty acid chains

Question 7

What bile made and what does it do?

Answer 7

The liver
Emulsifies lipids

Question 8

What is the process in which lipids are absorbed?

Answer 8

Lipid droplets are emulsified into monoglycerides and fatty acids with bile salts called micelles
Monoglycerides and fatty acids are absorbed into the epithelial cells
They are modified in the SER and join with a protein in the Golgi to become chylomicrons
They then enter a lacteal which transports them away from the intestine into the capillarys
