Allies And Enemies: How The World Depends On Bacteria

547 Words3 Pages

Microorganism is living organism( such as bacteria, fungi, viruses) too small to be seen with naked eye but visible under a microscope. Also called But as long as humans microbe(Dictionary.com)can’t live without carbon, nitrogen, protection from disease and the ability to fully digest their food, they can’t live without bacteria, said Anne Maczulak , a microbiologist and author of the book “Allies and Enemies: How the World Depends on Bacteria”(FT Press,2010)
Microorganisms are crucial because they play a vital role in many processes that involve human life and health. They are present in nature as well as in synthetically produced products designed to improve life.

Firstly, Eukaryotic cells are all cells which have a nucleus. All animal, plant and fungi cells, for example, are eukaryotic. On the other hand, bacteria are prokaryotic: they have no definitive nucleus. Eukaryotic may have membranes within the cell which form part of encapsulated organelles e.g mitochondria and chloroplasts whereas prokaryotic only have one cell: cell surface membrane. The spherical shaped of mitochondria with folded inner membrane forms cristae which is the site of ATP production. Almost all cell activities that require energy are driven by ATP. In Prokaryotic, DNA is free in cytoplasm, in the form of a single loop called a circular chromosome as well as some smaller DNA loops called plasmids

Deadly Companions: How Microbes Shaped Our History By Dorothy Crawford

816 Words | 4 Pages

Although microscopic single-celled organisms inhabited earth long before humans evolved from their primate ancestors, they continue to coexist and coevolve with humans today, flourishing as both harmless and deadly companions. Within her literary work Deadly Companions: How Microbes Shaped Our History, microbiologist Dorothy Crawford begins with a dramatic account of severe acute respiratory syndrome (SARS), the first pandemic of the twenty-first century. Crawford travels back in time four billion years ago to the origin of microbes, recounting the evolutionary history of microbes, showing how microbes spread and cause epidemics, and revealing how coevolution yields host resistance. Furthermore, Crawford explores the intertwining history of microbes and humans, with the purpose to reveal the link between the emergence of microbes and the cultural development of man.

Missing Microbes Summary

844 Words | 4 Pages

In the book Missing Microbes, the author, Dr. Martin J. Blaser discusses different types where the mysterious microbes are to be found. Dr. Martin also discusses his hypothesis in which talks about how over use of antibiotics has permanently changed the microbiome that humans live in, causing an increase in more modern diseases. The way Blaser lays the book is more like a journey; he traces his footsteps, and has the readers following the lead anxiously waiting on what he will inform them. There are a lot of doors in Science. Dr. Blaser chose to enter the door where facts and stories are to be learned everyday, in which there is no end, making that the beauty of science.

Some Of My Best Friends Are Germs Analysis

283 Words | 2 Pages

In the article, “Some of My Best Friends are Germs” Michael Pollan emphasizes the importance of microbes and how they affect our bodies and health. I thought a lot of this information to be interesting such as how microbes make up 99% of our bodies and how they contribute to the way we metabolize foods. I wasn’t aware of how microbes such as bacteria outnumber our body’s cells but yet fascinatingly interact with host cells to create optimal health. It was surprising to read that gut bacteria can alter the way we store fat or the way we respond to hormones that make us feel hungry or full which can ultimately lead to obesity because most often we hear that its due to an unhealthy lifestyle.

In the first four chapters of Deadly Companions author Crawford takes us on a journey on how microbes shaped our history. Starting with when microbes first appeared on planet Earth to Darwinian evolution of single celled organism. In chapter two “Our Microbial Inheritance” she discussed the relationship of microbes with hunter-gatherers and early settlements; and their relationship to disease. She looks at the impact of microbes on the lives of individuals and the population as a whole. Hunter-gatherers were small groups of people that hunted for food, moving from place to place.

The Ultimate Social Network Jennifer Ackerman Summary

435 Words | 2 Pages

The Ultimate Social Network In the article “The Ultimate Social Network” by Jennifer Ackerman it states that bacterial cells in the human body out number human calls ten to one. Now, that might sound scary. However, Ackerman also states that microbiome does not threaten us but offers vital help with basic physiological processes from digestion to growth to self-defense. By recognizing microbes in the body scientists can identify the specific effects of these microbes. And by doing this they can gain a new view of how our bodies function and why certain disease, such as obesity and autoimmune disorders, are on the rise.

Summary Of The Ultimate Social Network By Jennifer Ackerman

619 Words | 3 Pages

The author starts by explaining the human microbiome and the research on it. For many years, biologists thought that the human body was able to perform all of its important functions by itself. However, in the past decade, they have found that the human body contains trillions of microorganisms that help with these important processes. In fact, they outnumber human cell 10 to one. At first, microbe research was only focused on harmful pathogens, but recently, biologists have figured out what the most common bacteria in the human body are, and have been trying to figure out the specific functions of theses microorganisms.

Differences: The Disadvantages Of Prokaryotes And Eukaryotes

786 Words | 4 Pages

This essay will be discussing the differences in the two cells with reference to the metabolic processes and storage of genetic information. The most obvious difference is the nucleus and the lack there of a nucleus. In prokaryotes, there is one long chromosome or circular DNA called the nucleoid. This results in the DNA being much simpler than

Prokaryotes Vs Eukaryotes Essay

794 Words | 4 Pages

There are many structural differences between eukaryotes and prokaryotes that prove eukaryotes to be far more advanced than prokaryotes. The “focal point” for this assignment is on both types of cells and exploration of their structures proving why eukaryotes are more progressive than prokaryotes. The variance among the structures of prokaryotes and eukaryotes is considered to be the most important distinction between groups of organisms. The major difference between eukaryotes and prokaryotes is that eukaryotes have their DNA contained within a “TRUE” nucleus, while the genetic material in prokaryotes is not membrane-enclosed. The nuclear membrane is important as it provides protection for the genetic material; it also provides protection against Ultraviolet light, which in turn allows them to be in the sunlight.

Aerobic Respiration Process

1706 Words | 7 Pages

Microbes are also responsible for processes like photosynthesis which are very important because they provide living organisms with oxygen which is very crucial for processes like respiration. Additionally, this module is important in terms of research because as known more and more microbes specifically bacteria are becoming resistant to the different antibiotics. As such, more research is required to improve the treatment used for fighting or destroying these strains. Moreover, the microbes are changing and adapting all the time, this could be owed to the changing temperatures which affect their usual environment. So research is required to find out about the changes and how the available treatment can be modified to fight off these new strains that are developing.

Hindering a problem is easier than solving a problem. In other words, the best way to find a solution to an issue is to create a way where that issue would not be able to exist in the first place. With disease being a major obstacle for all life here on Earth, it was imperative for scientists to find a procedure that would eradicate it at its root. For as long as human have existed, microscopic organisms have dominated their well-being. These microorganisms consist of bacteria, fungi, protozoa, and viruses and their function is nothing besides to cause total havoc.
