3. How does fluoroquinolone affect bacterial cells but not eukaryotic cells?
Valentin [98]

Answer:

In order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples.

Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.

Which statement correctly describes amphipathic (or amphiphilic) helices and sheets?Helices are typically hydrophilic on one sur
Sloan [31]

Answer:

The correct answer is the last statement.

Explanation:

Amphipathic refers to a substance that comprises both hydrophobic and hydrophilic surfaces. Thus, the given first three statements are incorrect. The amphipathic helices are witnessed on the proteins surfaces in which the hydrophilic region associates with the aqueous phase and the hydrophobic regions associate with the hydrophobic component of the protein.  

Both the amphipathic sheets and helices exhibit primarily the hydrophobic or hydrophilic residues on one face. Thus, the correct answer is the last statement.
