  • Citric Acid Cycle Research Paper

    The citric acid cycle generates energy from the oxidation of various fuel molecules to acetyl coenzyme A (acetyl CoA). Acetyl CoA undergoes several redox, hydration and decarboxylation reactions to produce carbon dioxide (CO2), reduced nicotinamide adenine dinucleotide (NADH), reduced flavin adenine dinucleotide (FADH2), adenosine triphosphate (ATP) and hydrogen ions. The citric acid cycle links glycolysis which produces pyruvate from glucose and oxidative phosphorylation which generates ATP…

  • Cellular Respiration Level 3 Analysis

    This process occurs in the mitochondria of the cell. At the end of glycolysis, two pyruvates with extractable energy are left. The oxidation of pyruvate is used to catch remaining energy from ATP although no ATP is specifically produced in this step. There are three substances that pyruvate can be converted to, lactate which is anaerobic, acetyl CoA which is aerobic, and ethyl alcohol which is anaerobic. Oxygen is needed for the conversion from the pyruvate to the acetyl CoA and CO2. This…

  • Slide Two: Aerobic Metabolism Analysis

    Function The pyruvate enzyme is formed in the glycolysis process by the breakdown of glucose by oxidation. The Pyruvate complex converts the pyruvate to acetyl-CoA (Wiley, 2015). This occurs in several steps; first, pyruvate is decarboxylated by the PDC with help from the TPP (UC Davis, nd). Carbon from the TPP is then oxidised and transferred to the acetyl group. The E2 protein oxidises the product hydroxyethyl to acetyl and transfers acetyl to CoA, forming acetyl-CoA. NAD+ is reduced to NADH…

  • Fatty Acid Synthesis

    gluconeogenesis is high. Secondly, glucokinase is normally insensitive to glucose due to its high Km value. During fed state when the blood glucose level is above 6mM, insulin stimulates glucokinase transcription and availability. The hormone also stimulates fatty acid synthesis in the liver mitochondria by activating acetyl-coA…

  • Lipogenesis In Sepsis Case Study

    down into acetyl-CoA. Since acetyl-CoA can’t cross the membrane of the mitochondria, it has to first react with oxaloacetate to form citrate. Citrate can then cross the membrane into the cytosol when there are high levels of citrate in the mitochondria or by using the malate shuttle.⁶ Citrate lyase cleaves citrate into oxaloacetate and acetyl-CoA. Acetyl-CoA is the precursor for fatty acid synthesis. The 16-carbon fatty acid, palmitic acid, is the main end product of de novo lipogenesis. To…

  • P Toluidine Synthesis Analysis

    Benzocaine was synthesized from p-toluidine in a four step synthesis. Each intermediate product, including N-acetyl-p-toluidine, p-acetamidobenzoic acid, and p-aminobenzoic acid, was checked for yield, presence, and purity through weighing, taking IR and NMR spectrums, and determining the melting point. Thin Layer Chromatography was used to ensure the completion of the final reaction from p-aminobenzoic acid to benzocaine. The yield of the first step from p-toluidine to N-acetyl-p-toluidine was…

  • L-Ornithine Research Paper

    Recent studies have illustrated that C. glutamicum might be more advantageous as an L-ornithine overproducer [16]. In C. glutamicum, the L-ornithine biosynthetic pathway is cyclic due to L-ornithine acetyltransferase (OATase, encoded by argJ; EC, which catalyzes the conversion of N-acetyl-L-ornithine and L-glutamate to L-ornithine and N-acetyl-L-glutamate (NAG). NAG kinase (NAGK, encoded by argB; EC then phosphorylates NAG in the second step of the pathway. Besides OATase and…

  • Three Elements Of Carbohydrates: Glycogen, And Protein

    building body and provide energy (Howard 56). There are two types of vitamins: the fat-soluble, which are stored in the body tissues reserved for future use. On the other hand, the water-soluble vitamins do dissolve in fluids and are not stored. The fates of Acetyl CoA after metabolism Acetyl-CoA pathway starts with the reduction of Co2 to carbon monoxide “while the other Co2 is reduced to a carbonyl group” (Finch 10). The main enzymes involved in these processes are the Acetyl-CoA synthase…

  • Krebs Cycle Metabolism

    III )Krebs cycle The Krebs cycle consists of five major points . There is in firstly the general overwiew of cellular respiration and in secondly mitochondrie structure then Acetyl-Coa wich contains Production and possible fates then Krebs Cycle wich contains reactions and regulation and finally Glyoxylate cycle. For the general overwiew of cellular respiration we will talk about cellular respiration. Cellular respiration is an aerobic phase of catabolism in which organic fuel molecule are…
