Cell Wall & Capsule

Peptidoglycan is referred as

• Heteropolymer, glucon
• Heteropolymer, glucan
• Homopolymer, glycan
• Heteropolymer glycan

Other name for peptidoglycan

• Sacculus
• Murein
• Pseudomurein
• Both a and b

The term "pseudomurein" refers to the cell wall of

• Bacteria
• Archaea
• Protozoa
• murein removed cells of a bacteria (sphaeroplast)

The term cell envelope is comprised of

• Sacculus
• Cell wall and outer membrane
• Cell wall, outer membrane, cell membrane
• Glycoclayx, outer membrane, cell wall & cell membrane

The monomer of peptidoglycan

• N acetyl muramic acid & N acetyl glucosamine
• murein
• N-acetyltalosaminuronic acid & N acetyl glucosamine
• N-acetyl diamino pimelic acid & N- acetyl glucosamine

The type of bond or linkage associated with the monomers of the peptidoglycan in Bacteria & Archaea

• 1,4 α glycosidic linkage & 1,3 β glycosidic linkage

• 1,4 β & 1,3 β glycosidic linkage

• 1,4 β & 1,6 β glycosidic linkage

To which organism this cell wall polysacchrides belongs to

• Bacteria

• Bacteria & Archaea

• Archaea

• Plant

In a cell wall of Gram positive and Gram negative bacteria the amino acids side chains linked by

• pentaglycine interbridge & direct linkage between amino acid 3 & 4

• Pentaglycine interbridge & direct linkage between amino acid 4 & 3

• direct linkage between amino acid 3 & 4 & pentaglycine interbridge

• direct linkage between amino acid 4 & 3; pentaglycine interbridge

Three dominant amino acids present in cell wall of the Gram positive & Gram negative cells are

• D-alanine ; L-alanine ; D-glutamate
• Lysine; diamino pimelic acid ; D-alanine
• D-glutamine; D-lysine; D-alanine
• Lysine; D-glutamine; D-alanine
