Cell biology

Discussions Bag A stimulates cell whose contents are hypotonic to its environment. The situation is because the concentration of the dissolved substances in the cell is less than the surrounding media. In this case, the cell contents contain 1% sucrose solution that is less concentrated than the 50% surrounding media. Therefore, a large concentration gradient develops between the two media. Consequently, because of the high concentration gradient, the bag loses water faster and this leads to its…

Eric Lefkofsky is a graduate of the University of Michigan, he is an adjunct professor at the University of Chicago, he is the Co-Founder and CEO of Tempus a company with the technology and an operating system to gather data to be more effective in the treatment for Cancer and other illnesses. Eric Lefkofsky has twenty years of experience in the advances of technology. He believes that the health system is lacking sufficient data and information to treat patients differently, and depending on…

The Nova episode, “Cancer Warrior” follows the cancer Research of Dr. Judah Folkman, and his lab’s crowning achievement, defining the role of angiogenesis in tumors. Over the years that Dr. Folkman’s lab worked on the angiogenesis project they made many breakthroughs, albeit over a long period of time. Dr. Folkman was the son of an Ohio Rabbi, but instead of going into the family business he chose to practice medicine. After graduating from medical school Dr. Folkman was drafted into the United…

Phagocytosis: The effects of time and Latrunculin on endocytosis. Introduction Phagocytosis is a process in which cells engulfed foreign materials. Eukaryotic cells can engulf different particles and solutes from their environment using a variety of mechanisms called endocytosis. Some cells can carry out large endocytic processes called phagocytosis and micropinocytosis. These processes can internalize particles (>0.5um) whereas internalization of fluids through micropinocytosis mechanisms…

gene therapy. This was conducted with William French Anderson and his colleagues at NIH. They inserted a normal ADA gene into DiSilva’s T-cells and every two months about twenty five percent of her immune system function was restored so she can lead a normal life. The most interesting even that happen was in 1996 that the first mammal was cloned from adult cells. It was Dolly the sheep, and she died at the age of six because of a lung infection. Soon following that they…

Using Integrating Concepts in Biology (ICB)”, an introductory resource for this year’s electronic textbook, and answer the following discussion questions. Responses should be uploaded to Canvas by 11:59PM on 9/20/15. A PDF version of this guide is posted to Canvas, and can also be found in the e-text. 1. The ICB text is organized around five “big ideas” in biology. List them, then define the term that is bolded in the text of each one. The five big ideas in biology are 1: living systems…

both in the classroom and while shadowing a physician. While these two types of learning are very different, they both are vital aspects of having a holistic education in the biological sciences. Through my major in Cell Biology and Neuroscience, I have also been able to build on my biology foundation by delving more deeply into neuroscience, the facet of the life sciences that most interests me. I also have had hands-on experience working at the cellular level in my laboratory and have…

Robert Hooke was known for many things that have affected the world we live in, from the discovery of certain cell parts to laws that he has made. He was an important person to our history. Even though Robert Hooke was a philosopher, architect, experimenter, etc. He also had an interesting life before he became known to science. He discovered many different things, and has affected biology and how we see things in a different way. Robert Hooke was born in England on July 28, 1635. Robert…

Cellular respiration is a very interesting topic that we are currently learning about in our biology class. What makes this particular topic so remarkable are all of the different elements that work together for cellular respiration to occur in human beings and animals. In the video, “ATP & Respiration: Crash Course Biology #& 7.” (ATP & Respiration: Crash Course Biology #7. n.d.). The narrator does an excellent job of explaining the cellular respiration process in a very clear cut…

Taking Honors Biology in freshman year sparked a passion for biomedical sciences which has stuck with me over the past four years. This was enhanced by a Human Anatomy and Physiology course I took in 11th grade, where we learned about the how various human systems function. After taking this class, I decided to major in molecular biology, as I had only scratched the surface of the workings and biochemical interactions of cells, and was eager to continue learning. However, after a great work…
