Explain in a mechanistic manner how a disruption in cell membrane can affect life.

1 answer:

8 0

Eukaryotic cells have been confronted throughout their evolution with potentially lethal plasma membrane injuries, including those caused by osmotic stress, by infection from bacterial toxins and parasites, and by mechanical and ischemic stress. The wounded cell can survive if a rapid repair response is mounted that restores boundary integrity. Calcium has been identified as the key trigger to activate an effective membrane repair response that utilizes exocytosis and endocytosis to repair a membrane tear, or remove a membrane pore. We here review what is known about the cellular and molecular mechanisms of membrane repair, with particular emphasis on the relevance of repair as it relates to disease pathologies. Collective evidence reveals membrane repair employs primitive yet robust molecular machinery, such as vesicle fusion and contractile rings, processes evolutionarily honed for simplicity and success. Yet to be fully understood is whether core membrane repair machinery exists in all cells, or whether evolutionary adaptation has resulted in multiple compensatory repair pathways that specialize in different tissues and cells within our body.

Drug-resistant populations of microbes arise when: Group of answer choices exposure to drugs causes mutations that produce resis

yan [13]

exposure to drugs causes mutations which produce drug-resistant populations of microbes.

<h3>What is the effect of using same type of drug?</h3>

Drug-resistant populations of microbes arise when the exposure to drugs causes mutations because this exposure produce resistance which leads to mutation in the organism. Due to this mutation, the drugs did not work on the organism anymore.

So we can conclude that exposure to drugs causes mutations which produce drug-resistant populations of microbes.

100 POINTS!!!!

emmainna [20.7K]

Answer:

A) A medicine that is personalized towards an individual's DNA.

B) These new technologies will be a benefit towards human health because they will be more effective and will not be as hazardous.

2) The sequencing of the human genome changed the way doctors are analyzing personal disease and risk because they are now able to diagnose the disease risk factors, provide better treatment for patients, determine which type of disease it is more accurately, how much of a dose of medicine the patient needs, and figure out genetic disorders.

3) He is worried that people might be moving too fast regarding these developments and wants them to proceed slowly and carefully so there is no room for error.

4) Some benefits would be protection from other certain diseases, I can fix any sort of genetic disorder, and order it so I can become stronger. However, I’m concerned that there will be risks in the sequencing process, which will change my genome for the worse.

5) Many potential biomarkers have yet to be verified and qualified for use, the FDA has yet to set a regulatory approval pathway for these products, the success of personalized medicine is contingent the ability of scientists and healthcare providers to capture, manage, store, and provide access to data and medical information, in order for personalized medicine to succeed, healthcare providers, patients, and insurers must learn how it works, and there are many privacy, confidentiality and fair-use concerns.

6 It could influence the use of these technologies because rather than focusing on helping people, they will only think about the money, leading them to do it carelessly and recklessly.

A) I think that using the information in a person's genome to treat disease is a good idea because it is much more effective in preventing disease and can fix any sort of genetic disorder much more easily.

B) I think this should be controlled. To address the potential for loss of genetic privacy, make it so that person gives their consent and you only take what is needed without having to look at the whole genome.

Hope this helps
