Franklin Delaney Roosevelt essays

Franklin Delaney Roosevelt essays Born in 1882, Franklin Delaney Roosevelt, nicknamed FDR by the press, was born into a very wealthy family. He still remained to carry a genuine compassion for ordinary people and a great spirit of optimism which the country badly needed. He graduated from Harvard University and although his main interest was politics, he decided to take a job in a law firm. In 1920 FDR ran for Vice President but did not make it. The following summer, at the age of twenty-nine, he came down with polio, only to remain paralyzed for the rest of his life. Using steel braces and a cane, FDR, along with the help of his son and aides, remained to disguise the fact that he was crippled, reason being that he was too determined and strong-minded to show anybody his real weakness involving his health. FDR spent much time recovering at Warm Springs in Georgia, where this was sometimes his only escape out of his busy life. After his success as governor of New York, many supporters of FDR believed he should try for the presidency. So it was, in the election of 1932, FDR would b ecome president for the next twelve years. During the time when FDR was the United States president, there were two major crises in the hands of the nation. Although FDR promised many Americans that there would be no war with Germany, there certainly was; FDR tried to devise a plan with Churchill to defeat Hitler and have everlasting victory over this man. At this same time, FDRs assistant, Missy Halliand, suffered a stroke and was never the same again. FDR kept himself in his own state of loneliness, probably never to be the same man again. Three days after the U.S.S. Greer was fired on, FDRs mother fell sick and he sat by her side until she died. He would often ask his daughter Anna to take him to her grave where he would sit for hours; he found safeness and security when he was there. Shortly ...

The Most Abundant Protein

The Most Abundant Protein Have you ever wondered what the most abundant protein is? The answer depends on whether you want to know the most common protein in the world, in your body or in a cell. Protein Basics A protein is a polypeptide, a molecular chain of amino acids. Polypeptides are, indeed, the building blocks of your body. And, the most abundant protein in your body is collagen. However, the worlds most abundant protein is RuBisCO, an enzyme that catalyzes the first step in carbon fixation. Most Abundant on Earth RuBisCO, whose full scientific name is ribulose-1,5-bisphosphate carboxylase/oxygenase, according to Study.com, is found in plants, algae, cyanobacteria, and certain other bacteria. Carbon fixation is the main chemical reaction responsible for inorganic carbon entering the biosphere. In plants, this is part of photosynthesis, in which carbon dioxide is made into glucose, notes Study.com. Since every plant uses RuBisCO, it is the most plentiful protein on earth with nearly 90 million pounds produced every second, says Study.com, adding that it has four forms: Form I, the most common type is found in plants, algae, and some bacteria.Form II is found in different types of bacteria.Form III is found in some archaea.Form IV is found in some bacteria and archaea. Slow Acting Surprisingly, each individual RuBisCO is not all that efficient, notes PBD-101. The website, whose full name is Protein Data Bank, is coordinated by Rutgers University, the University of California, San Diego, and San Diego State University as a study guide for college students. As enzymes go, it is painfully slow, says PBD-101.  Typical enzymes can process a thousand molecules per second, but RuBisCO fixes only about three carbon dioxide molecules per second. Plant cells compensate for this slow rate by building lots of the enzyme. Chloroplasts are filled with RuBisCO, which comprises half of the protein. This makes RuBisCO the most plentiful single enzyme on the Earth. In the Human Body Around 25 percent to 35 percent of protein in your body is collagen. It is the most common protein in other mammals, too. Collagen forms connective tissue. It is found primarily in fibrous tissue, such as tendons, ligaments, and skin. Collagen is a component of muscle, cartilage, bone, blood vessels, the cornea of your eye, intervertebral discs, and your intestinal tract. Its a little harder to name a single protein as the most common in cells because the composition of cells depends on their function: Actin is a very common protein that is found in all eukaryotic cells.Tubulin is another important and abundant protein used in cellular division among other purposes.Histones, associated with DNA, are present in all cells.Ribosomal proteins are abundant since they are needed to produce other proteins.Red blood cells contain high concentrations of the protein hemoglobin, while muscle cells contain a high level of the protein myosin.
