A space between teeth not due to missing teeth. 4. A space between the upper central incisors in humans, or a space between two adjacent teeth in the same dental arch, especially that between the upper lateral incisor and the adjacent canine, into which the lower canine closes in the Carnivora, such as dogs.
Aerobic respiration. Definition. noun. (1) A form of cellular respiration that requires oxygen in order to generate energy. (2) The process of generating energy by the full oxidation of nutrients through Krebs cycle where oxygen is the final electron acceptor.Supplement.ith aerobic respiration, glycolysis continues with the Krebs cycle and oxidative phosphorylation. These post-glycolytic reactions occur in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells.
Glycolysis is the first stage of aerobic (and anaerobic) respiration. It takes place in the cytoplasm of the cell. In glycolysis (âglucose breakingâ), ATP is used to split glucose molecules into a three-carbon compound called pyruvate.erobic respiration occurs in the presence of oxygen, while anaerobic respiration does not use oxygen. Both types of cell respiration begin with the process of glycolysis, after which the two diverge.
