Predominantly multicellular not in bacteria but in human body
• Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body
• DNA occurs in a circular form in bacteria only
What else can I help you with?
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.
What is the ratio of bacteria to human cells?
In the human body, microbes:native cells can be anywhere from 10:1 to 20:1, though it may be closer to the lower end of this spectrum.
Does erythromycin affect human cells?
Yes, erythromycin can affect human cells by inhibiting protein synthesis in bacterial cells but can also affect human mitochondria due to their bacterial origin. This may lead to side effects in some individuals, especially at higher doses or with prolonged use.
Why pencilin does not harm human cells?
Penicillin targets the cell walls of bacteria, which are different from human cells. Human cells do not have cell walls like bacteria do, so penicillin does not harm them. This allows penicillin to selectively target bacterial cells while leaving human cells unharmed.
Why does penicillin not affect human cells?
This is essentially because bacterial cells and human cells are very different. Both bacterial and human cells use chemicals called enzymes to build their walls. Penicillin is the right chemical "shape" to chemically stick to part of the bacterial enzyme. When it does this, it stops the bacterial enzyme from working properly and this makes the bacterial cell walls weak. The weakened cell wall cannot withstand the outside pressure, it breaks up and the bacterial cell dies. Human cells are made by different types of enzymes with a different chemical shape that penecillin is unable to stick to so it cant stop the human enzymes from working. The human cell walls are thus unaffected by it and they remain strong.
Does the human body have more bacterial or human cells?
it has more human cells actually the human body has more bacterial cells. Although it may seem more likely that the human body would have more human cells than bacterial cells. -Vasillisa

What do bacterial cells and human skin cells plant cells have in common?
they all have numbers
What is the similarities of the respiratory system between a dog and human?
Both the human and grasshopper respiratory systems have structures called trachea that are lined with epithelial cells.

How are bacterial cell and human body cell similar?
Bacterial and human cells both have a cell membrane, cytoplasm, and genetic material (DNA). They both carry out essential metabolic processes for survival and reproduction. However, human cells are eukaryotic, meaning they have a nucleus and membrane-bound organelles, while bacterial cells are prokaryotic and lack these features.
What are the names of smallest cells?
mycoplasm which is a bacterial cell and human sperm cell are the smallest cells
What are the similarities between human cells and bacterial cells?
Predominantly multicellular not in bacteria but in human body • Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body • DNA occurs in a circular form in bacteria only
What are the similarities between human and pig anatomy?
There are very many similarities
In what ways are bacterial cells and human cells alike?
Bacterial cells and human cells are alike in that they both contain genetic material, have a cell membrane that regulates what enters and exits the cell, and have the ability to reproduce and grow. Additionally, both types of cells have ribosomes that are responsible for protein synthesis.
