through and will be obtained by oxygen (O2) to form into water (H2O). Oxygen also called terminal electron acceptor is necessary to remove electrons so other electrons can go through and to pump out protons (H+) for cellular respiration. An enzyme called ATP synthase provided protons energy to make ATP. Protons can only go through ATP synthase in a controlled way to go to the matrix of a mitochondria. ATP synthase makes ATP from adenosine diphosphate (ADP) and inorganic phosphate (Pi). In a…

to one another, each segment would consist of an oh group, a nitrogen, an R-CH3 and half of the Pi-Bond. The Chlorine is the same from all sides, and the rapid rotation of the pyridine group about the cobalt metal centre is so fast that all Methyl Protons feel it equally and as such are equivalent, for this reason the four methyl groups appear as one…

become based on its luminosity and temperature. In the nucleus of the condensed cloud, which could now fit within the orbit of Mercury at less than 58,000,000 km wide, electrons and protons are ripped from the atoms in the blistering one million degrees Kelvin now sustained in the central region. The electrons and protons now bounce around the interior of the forming star at energetic rates of hundreds of kilometres per second. Despite being quite hot, it is still far too cold yet to initiate…

Chapter-III OPERATING PRINIPLE AND LOSSES IN PEM FUEL CELL The polymer membrane is the heart of the PEM fuel cell which has some unique features. It allows protons but it is impermeable to gases, and hence it is known as a Proton Exchange Membrane. The membrane, which is squeezed between two electrodes (electrically conductive carbon cloths or carbon fiber papers) acts as electrolyte. A layer of catalyst particles (platinum) is placed at the interface between the porous electrode and polymer…

James worked alongside Rutherford when rutherford found the proton. James conducted an experiment in were the would fire the neutrons at a block of paraffin wax, which has a high concentration of hydrogen and is therefore rich in protons. In the experiment he discovered that some of the neutrons would be knocked out. James then took the opportunity to measure their energy. The discovery of the neutron…

range and are used when cancer cells are close to the skin. Both types of x-rays and gamma rays penetrate deeper than electrons, however the dose absorbed by the tissue decreases exponentially. For protons, as the depth increase so does the absorption. Unlike other types of particles, the peak for protons is very steep and only for a certain exact depth. The advantage of this pattern in energy deposition is that minimal energy is affecting healthy tissues as opposed to the malignant cancer…

The enzyme, succinyl coenzyme A synthetase, acts on the conversion of the succinyl group succinate. A decrease in the ATP production of the mitochondria may occur if there is a deficiency of this enzyme. The decrease is seen during the phosphorylation of succinyl CoA to succinate. With this decrease, the cells would produce lactic acid in order to get ATP leading the cell to be non-functional. The deficiency of the enzyme, and the increase in lactic acid causes fatal infantile lactic acid…

Experiment 7 Electrophilic Aromatic Substitution Of Salicyamide Name: Lidia Santiana Palha Student number: s3333523 Email-address: lidiapalha@gmail.com Name of demonstrator: H.Helbert Reaction Equation Summary Salicylamide and sodium iodide are dissolved in ethanol, and stirred and cooled to 0. After that household bleach was added while stirring vigorously, solution changed from colorless to pale yellow. Sodium thiosulphate and hydrochloric acid were added aswell.…

When the cell is resting (not stimulated), H+/K+-ATPases are located in vesicles inside the cell. When the cell is stimulated, these vesicles fuse with the plasma membrane, thereby increasing the surface area of the plasma membrane and the number of proton pumps in the membrane. Acetylcholine and histamine directly stimulate parietal cells to increase acid secretion. Gastrin stimulates acid secretion by stimulating histamine release from ECL cells. When the pH of the stomach gets too low,…
