  • Succinate Dehydrogenase

    Hypothesis Experiment I Eukaryotic cells contain several membrane-bound organelles. Plant cells are a specific type of eukaryote that are both aerobic and photosynthetic. Because of this, they contain mitochondria that serve a vital role in aerobic respiration that follows photosynthesis. The enzyme succinate dehydrogenase (SDH) is an enzyme associated with the Citric Acid Cycle that takes place in the mitochondrial matrix. SDH serves as a catalyst for a reaction in which succinate and FAD become fumarate and FADH2. The SDH-FADH2 complex then reduces Ubiquinone in the electron transport chain. SDH can be indirectly measured using the artificial electron acceptor DCIP that is blue in its oxidized state and colorless in its reduced…

  • Succinate Dehydrogenase Lab Report

    Abstract This experiment studies the rate of activity of succinate dehydrogenase protein derived from the mitochondria of cauliflower cells. Succinate dehydrogenase, once active, is known to reduce the coenzyme flavin adenine dinucleotide (FAD) to FADH2. Succinate dehydrogenase and its coenzyme creates an enzyme complex (E-FADH2) which transfers electrons to coenzyme Q during the Krebs cycle. In this experiment, sodium azide will be added to the mitochondrial solution to prevent the transfer of…

  • Mitochondria Experiment

    third strand of fly used was the sdhBEY12081 strain (mutant) that had a mutation present on the sdhb gene of the mitochondria. The sdhBEY12081 gene is responsible for producing the enzyme succinate dehydrogenase, which is used in the electron transport chain for ATP production. The results showed that the sdhb (mutant) strain of flies developed the quickest, the wild-type strain was second, while the W501 (hybrid) strain had the slowest developmental time. As regards climbing ability, the…

  • Reflection On Loneliness

    In response to #18 on application I believe myself to be rehabilitated in full. My incident was a time where I made a mistake that I never have before. Since that time, I have set hours to complete all community service and ordered counseling. I started my community service and counseling right away as I know how important it is to complete what is ordered. By December 10, I plan to have all community service completed. I am working at a community tutoring center and a state park in order to…

  • Survival Of The Sickest Analysis

    lowers the freezing point of the leftover water in the frog’s blood, which is moved into areas where ice crystals will cause the least damage so the frog is left unharmed. Much like how the wood frog survives cold conditions, the frequent urge to urinate and increased blood sugar in diabetics may have helped some of the Northern Europeans survive the extreme temperatures of the Younger Dryas. Favism, an inherited enzyme deficiency, is the most common enzyme deficiency in the world, and is…

  • Survival Of The Sickest By Moalem

    macrophages in people who have hemochromatosis surround foreign invaders, and since the bacterium have no iron, they starve to death in the body. People with the disease, although they will die later in life from iron buildup, can survive diseases that are potentially more harmful and survive long enough to pass the mutation on to their children after reproduction. This stronger defense system helps to fight off bacteria and other invaders, and helped many escape the bubonic plague, explaining…

  • Krebs Cycle Metabolism

    One things importants, the citric acid cycle is an amphibolic pathway. The krebs cycle a role in anabolism. For example the Anaplerotic reaction, these reactions replenish the intermediates of the citric cycle that are removed to serve as biosynthetic precursors. Thry are regulated to keep the level to intermerdiates high enough to support the activity of the citric cycle. And for finally we will talk about the glyoxylate cycle , the glyoxylate cycle catalyzes the net conversion of acetate to…

  • Citric Acid Cycle Research Paper

    The citric acid cycle produces energy by the oxidation of acetyl coenzyme A (acetyl CoA) to carbon dioxide (CO2) and ATP 3, 5, 7. Acetyl CoA can be synthesised from carbohydrates, fatty acids and amino acids.1, 5, 7. Pyruvate produced in glycolysis undergoes oxidation and decarboxylation by the multi enzyme complex pyruvate dehydrogenase to produce acetyl CoA. 7, 8, 10. The citric acid cycle also provides carbon skeletons for the biosynthesis of amino acids, fatty acids, carbohydrates,…

  • Cori Cycle Research Paper

    succinyl-CoA synthetase, succinate dehydrogenase, fumarase, malate dehydrogenase, and citrate synthase. The Cori Cycle has many parts to it ultimately leading to the breakdown of glucose and the diffusion of lactate with the liver. In the Cori cycle there is the conversion of glucose to lactate through anaerobic glycolysis in muscle cells, the diffusion of lactate from muscle cells into the bloodstream then being transported to the liver. To the conversion of lactate to glucose through…

  • Aerobic Respiration Lab Report

    Hypothesis: Aerobic Respiration: If a phosphate buffer, dichlorophenol-indophenol and succinate are added to a mitochondrial extract then the succinate molecules will bind to an enzyme complex (succinate dehydrogenase). Because the enzyme and FAD are a part of the same complex, initiating succinate oxidation, this reaction reduces FAD to FADH2. Thus the oxidation of succinate to furmarate. Anaerobic Respiration: If a solution of yeast and glucose is combined and placed in different incubation…
