Gerty Cori and her husband, Dr. Carl Cori, were the first people to receive a Nobel Prize in science. Gerty Cori was special because not only was she the third woman to receive a Nobel Prize, but she was the first in America. She was born to the Radnitz family in Prague on August 15, 1896. Her family was among a group of German-speaking Jew’s in the Austro-Hungarian Empire. Her father, Otto Radnitz, carved an austere path for her career because he was an affluent chemist; managing a sugar-beet refining business. He had a rigorous work ethic and wanted what was best for his children. Cori’s uncle, a professor in the pediatrics field, inspired her to go to medical school. She applied and was accepted to the German University of Prague as one of the few female attendees. In 1920, she and her soon to be husband at the time graduated with their M.D.’s. After graduating college, they were offered jobs to work in clinics in Vienna. Knowing that Europe would engage in war, they took measures into their own hands, and applied for jobs overseas in America. In 1922, they moved to New York, where Carl took a job at the State Institute for the Study of Malignant Diseases, and Gerty was hired as an assistant pathologist. Although they were discouraged from working with one another, they continued to anyways. They dedicated their work on how energy is created and transferred in the human body. Focusing in biochemistry, they began learning how glucose is metabolized. Gerty Cori influenced the modern world immensely with her various accomplishments and achievements throughout her lifetime such as the Cori Cycle and the Cori Ester. When the Coris began to study carbohydrate metabolism, it was believed that glucose, a type of carbohydr... ... middle of paper ... ...mes glucose-1-phosphate through the completion of phosphorylase, an enzyme. Glucose-1-phosphate develops into glucose-6-phosphate through the action of phosphorylase, which is another enzyme. Glucose-6-phosphate turns into glucose, and glucose turns into lactic acid, each step in turn interceded by one precise enzyme. The Coris' work improved the way scientists thought about reactions in the human body, and it advised that there were explicit, enzyme-driven reactions for many of the biochemical conversions that institutes life.

Rosalyn Sussman Yalow graduated Hunter College as the first women to graduate in physics (Bauman et. al. 2011). She also led a way for acceptance and understanding of women’s role in science in America (Bauman et. al. 2011). She even inspired Mildred Dresselhous, who was a professor at Massachusetts Institute of Technology (MIT) and president and officer of many Associations including American Association for the Advancement of Science, to pursue the career she wanted (Bauman et. al. 2011). Rosalyn born to Clara and Simon Sussman in New York City, on July 19, 1921 (Brody 1996). She married Aaron Yalow on June 6, 1943 and had two children named Elanna and Benjamin (Brody 1996). In 1977, Dr. Yalow won the Nobel Prize in medicine and was the second women to ever accept such an award (Brody 1996). She also taught physics in New York until 1950 when the Veterans Administration (during World War II) was interested in exploring and researching radioactivity (Brody 1996). As her life progressed, Dr. Rosalyn Sussman Yalow became an inspiration for young women who want to be recognized and achieve something in their life (Brody 1996). From when she was a child she was fascinated with science and decided to achieve something no women really does. Rosalyn Yalow went to school and started working in the science field, she managed to help the world of radioactivity and radioimmunoassay, how Mrs. Rosalyn impacted the world of science, how Dr. Yalow impacted the lives of other women, and how she never lost her passion for science even in her last years.

Marie Curie, a pioneer in her field and Nobel Prize winning Chemist, took a path that few women of her time dared and unfortunately, her passion for Science would be her ultimate demise. From birth to death Marie Curie lived a full life, with love, work, and passion at the center.
Describe how carbohydrates are digested and absorbed and how the body regulates glucose in the
Our body needs energy to carry out its functions properly. This energy is synthesized from the food we eat. Our body breaks down the food we take in and then build up the required materials for a healthy functioning of our body. Glucose, a simple sugar or monosaccharide that is the end product of carbohydrate digestion, is a primary source of energy for living things. (Taber’s, 2005). Glucose gets absorbed from our intestines and distributed by the bloodstream to all of the cells in our body. If the supply of glucose is more than required, our body stores the excess amount of glucose as glycogen, a chain of glucose. If there is shortage in other hand, our body uses the stored...
In Pauling’s own words he was “…a physicist with an interest in chemistry. [His] scientific work, however, has not been restricted to chemistry and physics, but has extended over X-ray crystallography, mineralogy, biochemistry, nuclear science, genetics, and molecular biology; also nutrition and various aspects of research in medicine, such as serology, immunology, and psychiatry” (Marinacci Ed., 1995, p. 26). Pauling received two Nobel Prizes acknowledging his contributions, one in Chemistry in 1954 and one for Peace in 1962.
One of the strongest women scientist/astronomer was born in 1818 as Maria Mitchell whom led an unbelievable life and had an incredible discovery. Maria Mitchell was born when women were not given the opportunity to vote nor did women have the same equal rights as men did, but given her circumstances of her father being a principal, founding his own school and being a distant family member of Benjamin Franklin she was given the same rights as the men did. Given a few obstacles she led an extraordinary life and became the first woman in America to work as an astronomer professionally, which she than later received an award personally from King Frederick VII, for her work and discovery.
Mileva "was born in Hungary in 1875, with a hip deformity and a good mind" (Storey 31). Although women did not usually pursue science degrees, she had won top marks in her class for math and physics, and was sent on to the Swiss Federal Institute of Technology in Zurich the same year as Einstein (Grenier B05). She was one of five in their class; Mileva and Albert both specialized in theoretical physics. Mileva attended classes and took notes for both of them. They studied for every class together. When they were apart, they wrote co...
Paul Ehrlich was born on March 14, 1854 in Strehlen Prussia. He was the son of a prosperous Jewish family. Ismar Ehrlich and Rosa (Weigert) Ehrlich, Paul's parents, were both from scientific backgrounds. It was not surprising that he had an attraction to the realm of science. Paul Ehrlich looked up to his cousin Karl Weigert. Paul began primary school at St. Maria Magdalena Humanistic Gymnasium at the age of six. He graduated at in 1872. After his graduation, he attended the University of Breslau for a semester then transferred to the University of Strassburg. With help
When most people think of the Scientific Revolution, they think of scientists such as Galileo, Newton, Brahe, and Boyle. However, many people do not even know about the many women who played a vital role in the scientific advancements of this period. Even when these women were alive, most of society either ignored them or publicly disapproved their unladylike behavior. Because of this, these women were often forgotten from history, and very little is known about the majority of them. Although their names rarely appear in history books, the female scientists of the Scientific Revolution still impacted the world of science in several ways. In fact, all of the scientists listed above had a woman playing an influential role assisting them in their research. However, assisting men in their studies was not the only role open to women; several women performed experimentation and research on their own, or advancing science in some other way, even though the society of the time looked down upon and even resisted their studies.
One of history’s most notable woman scientist of the late 15th century and early 16th century was none other than Sophia Brahe . Sophia Brahe was profound student in the sciences which included Medicine, Chemistry genealogy, and Astronomy. She had such a strong passion for science much like her brother who is known as a famous astronomer Tycho Brahe. It was through Tycho were Sophia learned the needed skills to uplift her scientific career.
The second step includes the conversion of glucose-6-phosphate into fructose-6-phosphate. Phosphoglucose isomerase is used within this part of the reaction because it helps the reaction to take place. During this reaction, the carbon-oxygen bond is rearranged, which is resulting in the transformation of the 6-membered glucose ring, into a 5-membered glucose
This lab attempted to find the rate at which Carbon dioxide is produced when five different test solutions: glycine, sucrose, galactose, water, and glucose were separately mixed with a yeast solution to produce fermentation, a process cells undergo. Fermentation is a major way by which a living cell can obtain energy. By measuring the carbon dioxide released by the test solutions, it could be determined which food source allows a living cell to obtain energy. The focus of the research was to determine which test solution would release the Carbon Dioxide by-product the quickest, by the addition of the yeast solution. The best results came from galactose, which produced .170 ml/minute of carbon dioxide. Followed by glucose, this produced .014 ml/minute; finally, sucrose which produced .012ml/minute of Carbon Dioxide. The test solutions water and glycine did not release Carbon Dioxide because they were not a food source for yeast. The results suggest that sugars are very good energy sources for a cell where amino acid, Glycine, is not.
In the liver and muscles, glycogen is produced from glucose by glycogenesis. Glycogen is stored in the liver and muscles glucose levels are low. When blood glucose levels are low, epinephrine and glucagon are secreted stimulating the conversion of glycogen to glucose (glycogenolysis). If there is an immediate need for energy upon glucose entering the cell, then glycoysis usually takes place. The end products of glycolysis are pyruvic acid and ATP. Since glycolysis releases small amounts ATP, further reactions continue to convert pyruvic acid to acetyl CoA and then citric acid in the citric acid cycle. The majority of the ATP is made from oxidations in the citric acid cycle in connection with the electron transport chain (3). This is how normal glucose metabolism takes place (figure-1).
