where do the different stages of cellular respiration take place?
cells
cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (atp), and then release waste products. the reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. cellular respiration is considered an exothermic redox reaction which releases heat. the overall reaction occurs in a series of biochemical steps, most of which are redox reactions themselves. although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow release of energy from the series of reactions.

dihydrolipoyl transacetylase participates in the pyruvate decarboxylation reaction that links glycolysis to the citric acid cycle. these metabolic processes are important for cellular respiration—the conversion of biochemical energy from nutrients into adenosine triphosphate (atp) which can then be used to carry out numerous biological reactions within a cell. the various parts of cellular respiration take place in different parts of the cell. in eukaryotes, glycolysis occurs in the cytoplasm, pyruvate decarboxylation in the mitochondria, the citric acid cycle within the mitochondrial matrix, and oxidative phosphorylation via the electron transport chain on the mitochondrial cristae. thus pyruvate dehydrogenase complexes (containing the dihydrolipoyl transacetylase enzymes) are found in the mitochondria of eukaryotes (and simply in the cytosol of prokaryotes).
