What is the difference between oxidative and substrate level phosphorylation? Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce ATP. Oxidative phosphorylation uses the electrochemical gradient‚ set up by the oxidation of nutrients‚ of protons across the inner mitochondrial membrane to generate ATP from ADP. During oxidative phosphorylation‚ electrons are transferred from electron donors to electron acceptors such as oxygen‚ in

small amount of lost product yields a great loss in the yield 4. These sources of error could be minimized by doing a larger reflux in order to increase the yield. However‚ as the purpose was to simply synthesis SnI4 in order to identify the stable oxidation states (the melting point range requires very little product) it would be advantageous to use the current method. This is due to the smaller quantity of materials needed for this type of reflux‚ thus making less of an environmental impact (using

THE GREAT METABOLIC RACE INTRODUCTION During exercise‚ carbohydrates and lipids are required in order to provide energy for the working body. The inherent reduced nature of these compounds allows for partial or complete oxidation in extracting energy in the form of adenosine triphosphate (ATP). The varying chemical structure of the macromolecules evokes different processes for their complete utilisation. This paper seeks to expound on the mobilisation of these fuels‚ the biochemical pathways that
