  • 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 which is used as energy for metabolic processes. The citric acid cycle is catabolic and anabolic. Fuel molecules are catabolised (broken down) to generate ATP. Anabolism is where molecules such as amino acids, fatty acids, porphyrins and many others can be synthesised from cycle intermediates. Cycle intermediates are…

  • The Citric Acid Cycle

    Abstract The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid cycle, is central to the formation of usable energy forms in cells. This essay will give detail on how this is achieved and the cycle’s links to other metabolic pathways such as oxidative phosphorylation. It will also explore how the cycle functions in anabolic and catabolic forms while replenishing used intermediates before examining how the cycle is regulated. Introduction The citric acid cycle being named…

  • Fermentation Lab Report

    Rafaela Hajdini Bio 104- 55 November 11th 2014 Fermentation Lab Report Abstract: Introduction: Cellular respiration is a reaction that the majority of living organisms partake in to get adenosine triphosphate (ATP), by obtaining chemical energy, to synthesize in three different phases; glycolysis, citric acid cycle, and the electron transport chain. Both glycolysis and the citric acid cycle are anaerobic pathways which means that oxygen is not need to form energy. However the…

  • Mitochondria Experiment

    Krebs Cycle, and the electron transport chain. Cellular respiration usually starts with a glucose molecule which is broken down in glycolysis into two pyruvate molecules, both of which consist of three carbons. This results in a total of 4 ATP molecules, while only 2 ATP molecules are needed to start glycolysis. As such, during glycolysis, overall 2 ATP molecules are produced. This process of glycolysis occurs in the cytoplasm. Each of the two pyruvate molecules then enters the Krebs…

  • Alkylated Polycyclic Aromatic Cells: The Effects Of PAH?

    2001). It has been suggested that effects of ROS on human cells may induce the oxidative injury leading to apoptosis (Salganik 2001). To study the relationship between ROS production and apoptosis, BaP-, DBT-, and Ret-induced ROS production in SK-N-SH cells was measured following exposure to CM-H2DCFDA, which forms a fluorescent oxidation product in the presence of ROS. Fig. ….shows the ROS levels after exposure to BaP, DBT, Ret, and H2O2 (positive control). A dose-dependent significant increase…

  • Chloroplast Research Paper

    Chloroplast are found in plants, they are responsible for the metabolism of energy to produce food for plants by breaking down Carbon dioxide, water and sunlight through a process called Photosynthesis. Once Carbon Dioxide enters a plant through stomata pores in a plant, water is absorbed through the roots of a plant and sunlight captured by chlorophyll pigments inside the chloroplast which is actually inside the thylakoids. It 's the russian doll complex., it is within the chloroplast that…

  • Aerobic Cellular Respiration Research Paper

    10/11/15 Nick Roberts Period 6 Cellular Respiration Aerobic cellular respiration is a process in which our cells get energy in the form of ATP. This process has 3 major steps in order to function properly. These steps are Glycolysis, Citric Acid or Krebs Cycle, and the electric transport state. These steps each have an important role in our cells respiration cycle. The first step in the cycle is called Glycolysis. Glycolysis takes place in the cytosol or cytoplasm of a cell. For…

  • Changing Temperature Lab Report

    Paragraph 1 The quartz type Iron (III) Phosphate (FePO4) evolves with the changing temperature from 294K to 1073K. From this, the polymorphic transformations in iron phosphate as a function of temperature can be observed. From iron phosphate, all the iron and all of the phosphorus are in tetrahedral coordination to oxygen. All of the iron and the phosphate are in tetrahedral coordinates. It also has a very open structure and has a lot of empty spaces. This means that as the temperature changes…

  • Demonstration Of Cellular Respiration

    Demonstration of Cellular Respiration Inside Lima Beans Cells in Vitro Purpose: Cellular respiration is a series of metabolic reactions that take place in the mitochondria and produce chemical energy in the form of ATP by the breakdown of food molecules.There are three processes involved in cellular respiration; glycolysis, the Krebs cycle and the electron transport chain. During this processes, glucose is oxidized by a series of redox reactions and its electrons and hydrogen ions are donated…

  • Hydroxynitrite Lab Report

    1. Introduction Hydroxynitrile lyases (HNL, EC 4.1.2.x) are enzymes which mediate the release of hydrogen cyanide (HCN) and aldehyde or ketone from cyanohydrins [1]. These HNL catalyse enantioselective synthesis and cleavage of cyanohydrins [2]. The cyanohydrins and their derivatives are finding wide applications in industries like pharmaceuticals, agrochemicals and cosmetics since these can be readily converted into other important molecules like α-hydroxy carboxylic acids, α-hydroxy ketones…
