Cell Wall

Question 1

The cell wall what’s composed

Answer 1

Peptido glycan

Question 2

What’s the components glycan in cell wall of bacteria

Answer 2

n.actylglucos amine and n.acetylmuramic amine acid

Question 3

What the type of bound between n.actyl glucosamine, n.acetylmuramic

Answer 3

B(1-4)bound

Question 4

Cross linking defin and dected place,

Answer 4

In n.acetylmuramic acid only link between glycan is a amino acid

Question 5

How amino acid in n.acetylmuramic acid link between others

Answer 5

by peptide inter bridge between amino acid in n.acetylmuramic acid

Question 6

Amino acids found only on n.acetylmuramic true or false

Answer 6

True

Question 7

Cell wall in Gram negative and positive

Answer 7

InGram negative is called (monolayer),
In Gram positive is called (multiple layers)

Question 8

What compounds in cell wall in negative and positive bacteria

Answer 8

In positive:-
teichoic found only in cell wall, lipoteichoic found in cell wall and cell membrane, linked between cell wall and cell membrane
In negative:-
No compound

Question 9

Added to bridge found in cell what is found

Answer 9

Found teichoic acid to more force attractive

Question 10
