Name: HyunSeon Do (Jane) ID#: 967201 General Biology 111L: Tuesday 12-2:30 pm Date: 10/26/15 Cellular Respiration and Fermentation Introduction: Cellular respiration are sets of metabolic reactions and processes that are taking place inside the cells that converts bio-chemical energies from food/nutrients into adenosine triphosphate ATP and after that release waste products. Energies are the forms of equally shared electron as reactant, and the products which form equally shared covalent bond, and during this process the potential energy was lost. So the respiration is the main way for a cell to gain useful energy to fuel its cellular activities. Most of the reactions occur in series of biological steps, a lot of these are redox reaction of themselves. We can define fermentation as a metabolic process that changes glucose into acids, gases and alcohol. There are two types of fermentation s. These are alcohol fermentation and lactic acid fermentation. These fermentations occur in yeast and bacteria, as well as in the muscle cells, after excessive use of muscle cells, cells are starved for oxygen, this is where lactic acid buil dup in the muscle cells. The process of fermentation normally happens without oxygen, and it does not go through the electron transport chain, this is the difference between fermentation and cellular respiration. During cellular respiration there are three main steps involved. First glycolysis, second the Citrix acid cycle, the third the electronShow MoreRelatedâ€Æ'Scie206 Biology Unit 2ip Photosynthesis Respiration1337 Words   |  6 PagesCarrie Cunnien SCIE 206 Biology January 20, 2013 IP 2 â€Æ' Abstract Some of the things that will be discussed are how photosynthesis and respiration are linked in order to provide you with energy from the food we eat. The absence of oxygen some cells and organisms can use glycolysis coupled to fermentation to produce energy to your cells. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions. â€Æ' Energy, Metabolism, and Cells Photosynthesis envelopes everythingRead MoreThe Effects of Temperture on Yeast Growth and Fermentation1212 Words   |  5 PagesIntroduction The purpose of this experiment is to determine the effect that temperature has on the growth and respiration of yeast fermentation. The growth and respiration of the yeast can be determined by using a glucose/ yeast solution mixed with water in flasks set at different temperatures. Yeast in order to produce, has to make energy, to carry out all cellular functions (Spicer, Holbrook, 2007). The concept that aerobic metabolism of all yeasts, is determined by the relative sizes of theRead MoreCellular Respiration Through Alcoholic Fermentation864 Words   |  4 PagesTitle: Showing Cellular Respiration through Alcoholic Fermentation Abstract: The experiment was conducted to determine the impact different yeast amounts had on yeast fermentation. It was hypothesized that the more yeast added the more CO2 would be produced. The carbon dioxide production was measured in the fermentation of yeast with solution of no yeast in test tube 1, 1mL yeast in test tube 2, and 3mL of yeast in test tube 3 over a period of twenty minutes. All of the yeast amounts producedRead MoreEnergy, Metabolism, and Cells – Photosynthesis Cellular Respiration1026 Words   |  5 PagesBiology – Science 206 Energy, Metabolism, and Cells – Photosynthesis amp; Cellular Respiration John Carter August 11, 2013 1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat. Photosynthesis can be defined as the process that living organisms such as plants use to translate the sun’s energy into chemical energy. Once the plant has translated the sun’s energy into chemical energy it then releases that energy and makes itRead MoreGeneral Biology : Genetic Test962 Words   |  4 PagesGeneral Biology I Genetic Test Essay Photosynthesis is an important process to living organisms because eliminates Carbon Dioxide and releases Oxygen by the use of a plant. Pigments are color molecules the absorb lights in different color wavelengths of light. The light that the pigments absorb turns into energy (Glucose) in the photosynthesis process. They are different types of pigments like Carotenoids, Anthocyans, Xanthophyll, and Chlorophyll which is the major light absorbingRead MoreMgc Practical Four Write Up. Brianna Golder-Dewar.

The class worked together to determine the specific measurements of gas that was produced over time using the fermentation tubes. During the second portion of this lab, Cellular Respiration was observed in a redox reaction converting succinate into fumarate. Di-chlorophenol, also known as DPIP was used to represent an electron acceptor that collects the Hydrogen ions released by the r edox reactionRead MoreHow Are Fungi Microorganisms?809 Words   |  4 Pagesmicroorganisms. True yeasts are unicellular and reproduce mainly by budding (The Columbia Electronic Encyclopedia, 2004). Budding is an asymmetric division process of mitosis. Yeasts of the genus Saccharomyces are especially important to alcohol fermentation (The Columbia Electronic Encyclopedia, 2004). In baking, yeast is used to act upon carbohydrates to form carbon dioxide, which is necessary for dough to rise (The Columbia Electronic Encyclopedia, 2004). Yeast has also been used since earlyRead MoreIs Composting A Natural Fertilizer?1298 Words   |  6 PagesThe material for known as humus is very rich in nutrients and is used as a natural fertilizer. In aerobic respiration, cells oxidize organic compounds, obtaining the energy from the chemicals bonds which can later be converted to ATP. Then we have aerobic bacteria which is one of the most important organism in the composting process, breaking down organic material through aerobic respiration. In this case with leaves they are made up of cellulose which is made of glucose molecules.The vast majorityRead More`` Fuel Lines Of Tumors Are New Target `` By Andrew Pollack861 Words   |  4 Pagesarticle, the author explains that most healthy cells primarily undergo aerobic respiration to generate ATP. Dr. Warburg, the German biochemist and Nobel Prize winner who first noticed the glucose metabolism of tumors in the 1920s, noticed that tumors tended to use anaerobic pathway even when o xygen was present despite less efficiency at generating ATP. According to Matthew G. Vander Heiden, assistant professor of biology at the Massachusetts Institute of Technology, one of theories in explaining this
