Gram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm. The periplasm has a distinct oxidizing environment that allow certain key protein structural features to be formed. Can you identify an amino acid(s) that would be affected by this oxidizing environment? How would it be affected, and what structural features would be sensitive to this environment? Ca

What cell types would be able to grow on the ECM in the following situations? F- , Hfr , Mix   a) Streptomycin was not added to the ECM.   b) The ECM contains thiamine.   c) The ECM contains all 20 amino acids and all 5 nitrogenous nucleic acid bases

What are the effects of the different agar concentrations, the temperature, and the dye types on the rate of diffusion? How do these factors mediate in the observed diffusion?

Bacteria were originally classified as one Kingdom called Monera. Why are they now in two distinct kingdoms? Please explain.

Describe the cross - section side view of a Gram - negative cell . Clearly state where the following would be located or write the letters in order of appearance from the outside to the inside . If any of these structures are not present , make sure to leave them out . A ) peptidoglycan ; ( B ) periplasm ; ( C ) porin ; ( D ) LPS ; ( E ) teichoic acids ; ( F ) plasma membrane : ( G ) outer membrane : ( H ) nucleoid

Which of the following is typically found in aquatic bacteria, especially among phototrophic types, and used for positioning in the water column A) O gas vesicle B) O sulfur granules C) O nanotubules D) Oglycogen E) O metachromatic granules

What would be added to a flask with E.coli incubated in the presence of oxygen to allow the maximum amount of growth? And what would be added to flasks including E.coli incubated in the absence on oxygen to allow maximum amount of growth?

How does the membrane structure of hyperthermophilicArchaea differ from that of Escherichia coli and why is thisstructure helpful for growth at high temperature?

How does the shape of a bacteria cell affect the bacteria’s survival in the environment?  To answer this question: Calculate the surface-to-volume ratio of a coccus, assuming it is a perfect sphere. Where radius (r) = 0.91 μm. surface-to-volume ratio of a coccus = ________________   Calculate the surface-to-volume ratio of a bacillus, assuming it is a cylinder. Where r = 0.5 μm and height (h) = 4 μm surface-to-volume ratio of a bacillus = _________________________   The values provided for the radius of the coccus and the radius and height for the bacillus will give approximately the same volume for the coccus and the bacillus. However, the surface area will differ. Now compare the surface-to-volume ratio of a coccus to a bacillus calculated with these values. Which has the higher surface area for the same amount of volume? Considering the coccus and bacillus of equal volume from the question above,   Which is more likely to survive in a dry environment? Explain your answer.…
