Viral Infection Host Cell
851 wordsIt all started with a little tickling in my throat. I forged ahead, knowing all too well what that feeling meant, I was getting sick. I convinced myself to just not think about it and it would just go away. This whole time there was an army of alien species amassing in my bloodstream and older cells. They are horrifyingly ugly, like something straight out of H. R. Geiger's imagination. They writhe and twitch while they are on the hunt for one of your precious body cells. One can almost imagine t...

Daimler Benz Fuel Cell
2,486 words... ironically enough, oil refining. But hydrogen, like gasoline, must be manufactured: it bonds so easily with other elements that it doesn't exist naturally on Earth in pure form. The trouble is that while gasoline is sold in 200, 000 filling stations across the US, the hydrogen infrastructure is minuscule. The result is a chicken-and-egg dilemma: What manufacturers will market hydrogen-powered cars if hydrogen isn't available to drivers? What hydrogen producers will build more plants if hydro...

Amp Amp Neuromuscular Junction
1,706 words... e effects would lead to a decrease in the safety factor for neuromuscular transmission. The safety factor is the difference between the threshold needed to elicit an action potential, which is usually around - 45 mV and the actual end-plate potential amplitude, which is usually 70 - 80 mV, this is shown in figure 5. As a result of the reduced number of functional A ChR, the skeletal muscle becomes weakened. This weakness has four special characteristics: 1. It generally affects the cranial m...

Effects And Treatment Of Rheumatoid Arthritis
1,098 wordsRheumatoid arthritis (RA) is more than just arthritis. In deed, many doctors call it rheumatoid disease to emphasize its widespread nature. People with RA often describe feeling much as though they have a virus, with fatigue and aching acting on their muscles. It has been estimated that 2 million Americans with 60 % of them women, have rheumatoid arthritis (Brewer, Earl J, 2000).

White Blood Cells Cell Wall
1,297 wordsBacteria is a simple organism that consists of one cell. They are among the smallest living thing on earth. Most bacteria measures from about 0. 3 to 2. 0 microns in diameter, and can only be seen through a microscope. Scientist classify bacteria according to shape. Cocci are round and sometimes linked together. Bacilli look like rods, and Vibrios resembles bent rods. There are two types of spiral-shaped bacteria, spirochetes and spirilla. Bacteria exist almost anywhere you can think of. There a...

Ebola and Marburg viruses (filo viruses) are very similar in density, morphology, and odium dodecyl sulfate - polyacrylamide gel electrophoresis (SDS-PAGE) profile. As far as these particles are pleomorphism, it means that they can exist in many shapes. The Marburg virus is the causative agent of Marburg hemorrhagic fever. It relates to Ebola, and was first discov...

Year Old Man Back To Life
2,020 wordsCell Components Let's imagine clouds of cold fog billow up through a circular hatch in the top of a stainless steel tank as a biologist pulls out the lid and its one-foot thickness of styrofoam insulation. As the fog rolls down to the floor, Hay peers into the dark tank, where the temperature is all the time 321 degrees below zero Fahrenheit. It is kept so cold because that is a temperature at which life, normally warm and pulsing with activity, abandons its vital dance and enters limbo - but wi...

Some of these enzymes break down proteins, others attack fats, and still others disassemble the nucleic acids that make up DNA and RNA (Bourne, 1992, p. 123). Lynosomes don't always work right. When they fail, the result can be catastrophic disease. In Tay-Sachs disease, for example, victims have inherited a faulty gene, which leads to a defective enzyme or no enzyme at all. As a result certain undigested molecules accumulate in the lysosomes, gradually lead...

The word? clone? , derived from the Greek word? Know? , meaning twig or slip, refers to asexual reproduction. Also known as vegetative reproduction. Cloning became known to the public about 30 years ago. This idea of cloning about his time resulted in an experiment of the successful asexual reproduction. This experiment took place i...

Carbon Dioxide Cigarette Smokers
1,369 wordsJust as a fire needs oxygen to burn, the human body also needs a continuous supply of this essential element for the process of combustion that goes on constantly in every cell. We ordinarily do not think of a body metabolism as combustion, yet that is what is: the controlled burning of carbohydrates, fats, and proteins to provide energy. The job of the respiratory system is to furnish the oxygen that combines with these fuels in each of the billions of cells, and to carry away the waste product...

Passive Transport Active Transport
229 wordsThe membrane has a double lipid layer through which fat- soluble substances will move, by passive transport or diffusion. The molecules will only move through if they are small enough. There are globular protein regions, which are hydrophilic. These regions allow water and water soluble substances through, but only if they are small enough, for example starch grains are too big. These substances move through by passive transport or diffusion. Diffusion is the passive movement of substances from ...
