Describe the location of the citric acid cycle and oxidative phosphorylation in the cell Cellular respiration is a process that all living things use to convert glucose into energy. Nicotinamide adenine dinucleotide (NAD +) and flavin adenine dinucleotide (FAD) are coenzymes used in cellular respiration to transport high potential energy electrons to the electron transport chain (a step in oxidative phosphorylation) in the mitochondria. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis. Likewise, “biological machines” also require well engineered parts and good energy source in order to work.Perhaps the second most important molecule (DNA is the first) is adenosine triphosphate (also known as ATP).Basically, ATP serves as the main energy currency of the cell. Steps of Glycolysis process 06: Oxidative Phosphorylation of Glyceraldehyde 3-phosphate : There are two energy-conserving reactions of the process of glycolysis where step 06 is the first of them and step 09 is the second of them. NAD H --> NAD+ + H+ + 2e- the oxidative part is essentially each of the NAD H becoming oxidized in the electron transport chain as they loose their hydrogen, or as they loose their electrons. Cellular respiration, in this case, aerobic respiration (respiration that uses oxygen), can be divided into four different steps and oxidative phosphorylation is the final step in the cellular respiration process. Oxidative phosphorylation (UK / ɒkˈsɪd.ə.tɪv /, US / ˈɑːk.sɪˌdeɪ.tɪv / or electron transport-linked phosphorylation or terminal oxidation) is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing the chemical energy stored within in … Krebs cycle only occurs in aerobic conditions (with the presence of oxygen) in the matrix of the mitochondria.
