    The Electron Transport Chain (ETC) and Oxidative phosphorylation [VII] These processes are the last stages of cellular respiration. NADH and FADH will be transferred into the mitochondria. Oxidation takes place here. The electrons are freed. The electrons will travel through a system of four protein complex structures, known as the Electron Transport Chain. ATP are produced as a result of this transport chain as the electrons are the fuel that drive the oxidative phosphorylation. The presence of Phosphor binds to ADP to form ATP molecules. ETC and Oxidative phosphorylation occur in the mitochondria. In order to make ATP, ironically energy is needed. That is where FADH2 and NADH play their parts. They are oxidised when they enter the protein…

    Cellular respiration “is the process of breaking sugar into a form that the cell can use as energy” (simple.wikipedia). In Cellular respiration there are 3 steps. Glycolysis, Krebs cycle, and the Electron Transport Chain. “Cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All cells carry out cellular respiration” (hyperphysics). The cellular respiration equation is C6H12O6+6O2>6H2O+6CO2+ATP. These are the three steps of…

    adenosine triphosphate. C6H12O6(S) + 6O2(g) -----------> 6H2O(l) + 6CO2(g) + 38 ATP However, this equation is only true under the circumstance the organism has sustained three stages of respiration, including glycolysis, the Krebs cycle, and the electron transport chain. Both the Krebs cycle and electron transport chain occur in the mitochondria, and are aerobic, requiring the presence of oxygen. On the other hand, glycolysis occurs within the cytoplasm of…

    . Triglycerides are a form of lipid and are made up of 1 glycerol and 3 fatty acids. In order for a triglyceride to be broken down, it must pass through 3 stages; the Beta Oxidation Stage, the Citric Acid Cycle or CAC, and the Electron Transport Chain. Two byproducts of Beta Oxidation and CAC are NADH and FADH-2. These two byproducts go on to the Electron Transport Chain to create the energy called ATP. A fatty acid is made up of a chain of carbon and hydrogen bonds, which are hydrophobic, and…

    Introduction In the Foundations of Biology lab section everyone had to investigate cell organelles and cellular metabolism. Every quad or tri group had to test for the activity of a chloroplast electron transport chain. The two choices that were available for us to investigate was broccoli and pea seedlings. Our group was nominated to utilize 20 grams of broccoli florets to find fractions that composed of an abundance of chloroplast. Project 1 had 3 parts to it; this consists of fractionation…

    and F0 complexes together. The catalytic activity i.e. the creation of ATP from ADP and Pi takes place in the F1 complex, whilst proton transport happens in the F0 complex. The F0 complex is made up of mostly C subunits, these are crucial to binding protons and therefore to ‘pump’ the protons through the membrane. Any of the subunits that bind to the ATP synthase can be potential targets to help kill the bacterial. ATP synthase also has other targets that could be used as well such as the metal…

    It was noticed that the exp was in good acceptance with the theoretical value of PF leading to the conclusion that Frank-poole emission is the prevailing charge transport mechanism operating in these films. This can be due to the trap levels into the dielectric (Poole–Frenkel effect), which is responsible for the conduction through the charge carriers released from it, which enhances as the number of trap levels increases on increasing the time of reaction. This enhances the formation of…

    electrodes (they are called dees because they look like the letter D) in the vacuum chamber. This chamber is flat and sits in a narrow gap between poles of a large magnet creating a perpendicular magnetic field. A high frequency voltage is applied across the electrodes as a surge of charged particles is fed into the centre of the chamber accelerating the charged particles whilst attracting and repelling them. The magnetic field propels the particles spiral towards the edge of the chamber as…

    An atom made of thousands of electrons would have a very high, negative electric charge; however, this was not practical, as atoms typically have no charge. In 1906, Thomson suggested that atoms contained far fewer electrons, a number roughly equal to the atomic number. These electrons must have been balanced by a positive charge. Thus, Thomson began studying positively charged ions as he channeled a stream of ionized neon through a magnetic and electric field. He used deflection techniques to…
