Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.
Answer: Option B & C
<u>Explanation:</u>
Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.
On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.
Answer: Your answer is True.
Explanation:
Answer:
Here the fucose is linked to galactose by alpha1,2 glycosidic linkage.
Explanation:
Fucose is a deoxy sugar consist of 6 carbon atoms which means fucose is a hexose sugar.
Fucose does not contain -OH group at C6 carbon that"s why it is termed as deoxy sugar.
Fucose can link to both Nactylglucosame by alpha-1,6 glycosidic linkage and to galactose by alpha-1, glycosidic linkage generates the H antigen.
As donor is blood type B that means fucose is linked to galactoseof H antigen by alpha 1,2glycisidic linkage.
