For
each type of cell wall in bacteria (gram positive vs. gram negative
) describe the unique components present in each and list how each
layer of the cell wall is connected together ( what molecules
accomplish this)?
Compare and contrast the CELL MEMBRANE of
gram-positive and gram-negative cells.Be sure to include function,
structure, and characteristiques in your answer.
What are the differences in cell envelope structure between
gram-negative and gram-positive bacteria? How might these
differences become important if you wish to genetically engineer
bacteria to excrete proteins into the extracellular fluid?
1.
Gram postive bacteria differ from gram negative with respect to:
A. Cell wall composition
B. Pepitoglycan content
C. The presence of periplasm
D. All of the above
2. What advantages does a pour plate have over a streak plate
in terms of culture conditions?
A. A spread plate in anaerobic and a pour plate is
aerobic
B. A spread plates is aerobic and a pour plate is
anaerobic
C. A spread plate places the bacteria equidistance from one
another,...
1) Create a chart that compares and contrasts the structure of
gram-positive and gram-negative cell walls.
2) Gram negative bacteria are considered more harmful than gram
positive bacteria.What are the two reasons that contribute to this
situation due to the unique characteristic of the outer membrane of
Gram-negative bacteria? (Minimum length : 150 words)
describe the structure of a bacteria flagella and how is the
bacteria flagella different from a eukaryotic one?
Explain the following terms (in relation to bacteria flagella) –
Peritrichous, Monotrichous, Lophotrichous, and Amphitrichous
What are axial filaments – what microbes have axial
filaments?
