Digestion And Absorption

Question 1

Where is Enzyme Amylase produced?

Answer 1

Produced in Salivary Glands or Pancreas

Question 2

What is the function of Amylase?

Answer 2

Function of Amylase is to hydrolyse Starch to Maltose

Question 3

What are Membrane bound Disaccharides? And what are the different type of Membrane Bound Disaccharides are their?

Answer 3

Membrane Bound Disaccharides hydrolyse disaccharides to monosaccharides
The different type of Membrane-Bound Disaccharide are Maltase(Maltose) Sucrase(Sucrose)

Question 4

Where is Enzyme Lipase present?

Answer 4

Small Intestine

Question 5

What is the function of Enzyme Lipase?

Answer 5

Enzyme Lipase is to hydrolyse Lipids to Monoglycerides and Fatty Acids

Question 6

What and where is Bile Salt produced?
[2 Adaptation]

Answer 6

Bile Salt is made by the Liver
Bile Salt emulsify lipids giving it a large Surface Area so it can easily be hydrolysed by Enzyme Lipase
2) Products which remain associated with Bile Salt Form Micelles which travel to ileum and Brake down when in contract with EPITHELIUM so products diffuse straight into epithelium which increase Rate of Absorption.

Question 7

What is the advantage of Micelles ?

Answer 7

Micelles travel to ileum and are broken down when in contact with EPITHELIUM SO products diffuse straight into epithelium so INCREASE RATE OF ABSORPTION

Question 8

What is the function of Enzyme Protease?

Answer 8

Function of Enzyme Protease is the hydrolyse proteins(Polypeptide) into Amino Acids

Question 9

What is the function of EndoPeptidases?

Answer 9

The function Of EndoPeptidase is to hydrolyse Peptide bonds in the MIDDLE REGION of a polypeptide chain.

Question 10

What is the Function of Exopeptidase?

Answer 10

Function of Exopeptidase is to hydrolyse peptide bonds on TERMINAL Amino Acid

Question 11

What is the Function of Membrane Bound Dipeptidases?

Answer 11

Function of Membrane Bound Dipeptidases is to hydrolyse Dipeptides into 2 amino acids

Question 12

How is Amino Acid/Glucose and Monosaccharides transported into the Epithelium? And through what protein?

Answer 12

Co-Transport through CHANNEL PROTEIN.
Na+ DOWN concentration gradient.
AminoAcid/Glucose AGAINST concentration gradient
From lumen into Epithelium

Question 13

How is AminoAcid/Glucose and Na+ transported from Epithelium into Blood through what proteins?

Answer 13

1.First thing that happens is: Na+ actively transported into Blood through CARRIER Protein and K+ Actively transported from Blood into Epithelium
2.AminoAcid/Glucose FACILITATED DIFFUSED into blood through Channel Protein

Question 14

What is the advantage of Sodium-Potassium Pump? And what is it?
[IN ABSORPTION]

Answer 14

Sodium-Potassium Pump is when K+ actively transported into Epithelium and Na+ into Blood
NA+-K+ pump ensures FAVOURABLE CONCENTRATION of Na+ maintained from Lumen into Epithelium ENSURES transported into the Blood.

Question 15

Where do the Monoglyceride travel to and Recombine to form what?

Answer 15

Monoglyceride travel to Endoplasmic Reticulum and Recombine to form TRIGICLYCERIDE

Question 16

How are Lipids transported away?

Answer 16

Trigclyercerides and then packaged in GOLGI BODY and Combine with Proteins to form CHYLOMICRONS and travel to LACTEAL by EXOCYTOSIS and transported away from Small intestine
