It can also happen in the presence of oxygen, it just does not require it. The anaerobic respiration definition states that it is the pathway where the glucose is broken down into molecules in the absence of oxygen to produce energy. 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Anaerobic respiration occurs in the cytoplasm with a net production of 2 ATP molecules, results from incomplete oxidation of one glucose molecule. process of producing ATP by breaking down carbon-based molecules when oxygen is present. It employs an electron transport chain, with inorganic molecules other than oxygen used as a final electron acceptor. synthesizes carbohydrate molecules. Living things use this reaction (a process called respiration) to produce energy. Denitrification is the utilization of nitrate (NO 3 −) as the terminal electron acceptor. For this step, oxygen is needed in which further break down of glucose occurs to release entire energy stored in the glucose molecule. There are two types of cellular respiration: aerobic and anaerobic. As shown in the figure below, the first major step in producing ATP is glycolysis. Anaerobic respiration : does not use oxygen. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). With oxygen, organisms can use aerobic cellular respiration to produce up to 36 molecules of ATP from just one molecule of glucose. Glycolysis itself does not require oxygen, and therefore can continue in the absence of it. Anaerobic Respiration Some organisms do not need as much energy as others and sometimes the conditions do not allow for aerobic respiration run successfully. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose. What is it called when two tectonic plates rub against each other in opposite directions?
