bacterial cell structure

Question 1

eukaryotic and prokaryotic cell membrane strength
-sterols
-hopanoids

Answer 1

eukaryotic have sterols (cholerstral)
prokaryotes have hopanoids (important in oil)

Question 2

what gram positive and negative bacteria have transporters or porins

Answer 2

gram positive= transporters
gram negative= prorins

Question 3

what colour is gram positive
-size of petidoglycan layer on cell wall
-what does it contribute to

Answer 3

-purple
-thick layer
-contributes to biofilm production

Question 4

colour of gram negative bacteria
-size of peptidoglycan layer
what it contains
-function of periplasm
-lipopolysaccharide (LPS) only in gram negative

Answer 4

-pink
-thin layer
-contains porins, enzymes for nutrients and antibiotic resistence.
-site of enzymatic activity

Answer 5

function of glucosididc and peptide bond in peptidoglycan layer

Question 6

Why is the bacterial cell wall clinically significant?

Answer 6

It is a major target for antibiotics like β-lactams (e.g., penicillin)
