Explain why antibiotics are effective at killing bacterial cells but do not seem to have an impact on human cells eukaryotic cells Use at least two examples such as tetracycline erythromycin?
Antibiotics target specific structures or processes unique to bacterial cells that are not present in human eukaryotic cells. For example, tetracycline interferes with bacterial protein synthesis by binding to bacterial ribosomes, while erythromycin inhibits the bacterial ribosome's ability to make proteins. Since human cells do not have the same type of ribosomes or protein synthesis mechanisms, antibiotics like tetracycline and erythromycin do not affect human cells the same way they do bacterial cells.
Can cells live and reproduce in the presence of antibiotic?
Cells that are resistant to antibiotics can survive and reproduce in the presence of antibiotics. However, non-resistant cells are typically unable to survive and reproduce in the presence of antibiotics. This is why antibiotic resistance is a growing concern in the medical field.
How do antibiotics work on gram - negative bacteria?
Gram negative bacterial cells have an outer membrane that interferes with antibiotics and drug entry into the cell. The bacteria that are resistant to antibiotics are E. coli, salmonella, shigella, and Yersina. The first three affect the GI tract and the second causes the Black Death. These are resistant to penicillin. So ampicillin and streptomycin are used.
Is Damage to nucleic acids part of antimicrobial agents affect cellular structures?
Yes, damage to nucleic acids by antimicrobial agents can affect cellular structures by disrupting processes such as DNA replication, transcription, and protein synthesis. This can ultimately lead to cell death or impaired function in microorganisms.
What compound kills bacteria without harming the cells of humans?
Antibiotics such as penicillin and tetracycline are effective in killing bacteria by targeting specific bacterial cell components that are absent in human cells, thus reducing the risk of harm to human cells. However, misuse or overuse of antibiotics can lead to antibiotic resistance in bacteria, diminishing their efficacy over time.
Why don't antibiotics kill your cells when you take them?
Usually, antibiotics don't kill your cells if the biotic isn't strong enough.
What is microbial control?
Microbial control refers to the methods used to reduce or eliminate microorganisms such as bacteria, viruses, and fungi from an environment. This can be achieved through physical methods (such as heat or UV radiation) or chemical methods (such as disinfectants or antibiotics) to prevent the spread of infectious diseases or maintain a sterile environment.
What are the cells that make antibiotics?
Antibiotics are chemically synthesized compounds. They are not made by cells
What do antibiotics do to living cells?
Antibiotics are designed to kill cells, some are targeted on certain types of cells, some aren't.
How nuclear power and microbial fuel cells work?
photosynthesis
Are viral paricles smaller than microbial cells?
Yes.
What is the difference between Benthic Microbial Fuel Cell Microbial Fuel Cells Is there a difference?
Benthic Microbial Fuel Cells are basically a microbial fuel cell. Instead of the anode being placed deep into sediment [MFC]- the anode is placed in a chamber where monitored amounts of neutrients/fresh water can enter and be controlled [BFMC]
What problems are there with microbial fuel cells?
Some challenges with microbial fuel cells include low power output, slow reaction rates, and high production costs. Additionally, maintaining a stable microbial community within the fuel cell can be difficult, leading to fluctuations in performance and efficiency.
Do antibiotics target prokaryotic or eukaryotic cells?
Antibiotics target prokaryotic cells, such as bacteria, by disrupting their cellular processes or structures. They do not typically target eukaryotic cells, which include human cells, because they have different cellular structures that antibiotics do not affect.
Do plant cells produce antibiotics?
YES!
Explain how hypertonicity can be used as a means of controlling microbial growth?
Hypertonicity can be used to control microbial growth by creating a high-salt or high-sugar environment that causes water to leave microbial cells, leading to dehydration and cell death. This process disrupts the microbial cells' ability to function properly and inhibits their growth and reproduction.
What are immobilized cells?
microbial or other cells can be immobilised by calcium alginate as in case of immobilised enzymes. these cells are entrapped in gel and are immobilised and have different applications
