Bacteria Morphology Gram positive cells have a multiple layer of peptidoglycan that helps to retain the crystal violet stain second outer membrane that helps to retain the crystal violet stain thick capsule that traps the crystal violet stain periplasmic space that traps the crystal violet multiple layer of peptidoglycan that helps to retain the crystal violet stain second outer membrane that helps to retain the crystal violet stain thick capsule that traps the crystal violet stain periplasmic space that traps the crystal violet ANSWER DOWNLOAD EXAMIANS APP
Bacteria Morphology The last step in synthesis of peptidoglycan is binding of penicillin to a membrane protein attachment of a portion of peptidoglycan to a membrane lipid attachment of a peptide to muramic acid attaching two amino acids to form a cross-link binding of penicillin to a membrane protein attachment of a portion of peptidoglycan to a membrane lipid attachment of a peptide to muramic acid attaching two amino acids to form a cross-link ANSWER DOWNLOAD EXAMIANS APP

Bacteria Morphology The cell walls of Gram positive bacteria contain two modified sugar, viz. N- acetylgucosamine (NAG) and N- acetylmuramic acid (NAM). They are covalently linked by β- 1,4-glycosidic bond β-1,6-glycosidic bond α- 1,6-glycosidic bond α- 1,4-glycosidic bond β- 1,4-glycosidic bond β-1,6-glycosidic bond α- 1,6-glycosidic bond α- 1,4-glycosidic bond ANSWER DOWNLOAD EXAMIANS APP
