Often asked: Which Of The Following Cellular Components Would Not Be A Good Target For An Antibiotic?


What cellular structure would be a good target for antibiotics?

In principal, there are three main antibiotic targets in bacteria: The cell wall or membranes that surrounds the bacterial cell. The machineries that make the nucleic acids DNA and RNA. The machinery that produce proteins (the ribosome and associated proteins)

What cellular structure do antibiotics typically target quizlet?

Antibiotics with this MOA target peptidoglycan cross-linking/formation in the bacterial cell wall.

Which of the following cellular components is not part of a prokaryotic cell?

Explanation: Prokaryotic cells are simple cells that lack membrane-bound nuclei and complex organelles. Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes.

Which of the following structures would you not find in a bacterial cell?

Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm.

How a unique cell structure of a microbe could be a target for antibiotics?

Most bacteria have cell walls consisting of single or more protective layers on top of their cytoplasmic membranes. These cell walls protect them from antibiotics, but also provide good targets for antibacterial drug discovery.

What is the best antibiotic for a bacterial infection?

Bacterial infections are treated with antibiotics such as amoxicillin, erythromycin and ciprofloxacin. There are many different types of antibiotic, with different ways of working; the choice depends on the type of infection you have. Fungi commonly cause skin infections such as athlete’s foot and ringworm.

Why do antibiotics not affect human cell translation?

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.

What type of microscope would be best for studying the detailed structure of the surface of a plasma membrane?

A transmission electron microscope would be ideal for viewing the cell’s internal structures, because many of the internal structures have membranes that are not visible by the light microscope.

Which feature of a bacterial cell is attacked by many antibiotics?

Many antibiotics, including penicillin, work by attacking the cell wall of bacteria. Specifically, the drugs prevent the bacteria from synthesizing a molecule in the cell wall called peptidoglycan, which provides the wall with the strength it needs to survive in the human body.

What 4 cell components are found in all cells?

All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4 ) ribosomes,

What is the main characteristics of prokaryotic cell?

Prokaryotes lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shape, and prevents dehydration.

What 4 organelles are found in all cells?

Explanation: There are four types of Eukaryotic cells: Animal, Plant, Fungi and Protists. Together, they ususally have these organelles in common – the nucleus, mitochondria, golgi apparatus, ribosomes, endoplasmic reticulum, peroxisome and vacuole.

What is the basic structure of a bacterial cell?

In bacteria, the cell wall forms a rigid structure of uniform thickness around the cell and is responsible for the characteristic shape of the cell (rod, coccus, or spiral). Inside the cell wall (or rigid peptidoglycan layer) is the plasma (cytoplasmic) membrane; this is usually closely apposed to the wall layer.

Which of the following is not present in bacteria?

mitochondria and golgi body are not present in bacteria. Both mitochondria and golgi bodies including other cell organelles are lacked in bacteria.

What characteristics are used to classify bacteria?

When identifying bacteria in the laboratory, the following characteristics are used: Gram staining, shape, presence of a capsule, bonding tendency, motility, respiration, growth medium, and whether it is intra- or extracellular.
