Where organelles does anaerobic respiration take place?

Anaerobic respiration primarily occurs in the cytoplasm of cells, where glucose is broken down without the use of oxygen. In eukaryotic cells, this process can occur in the absence of mitochondria, as it does not require the organelles associated with aerobic respiration. In some organisms, such as yeast, anaerobic respiration also leads to the production of ethanol and carbon dioxide. Overall, the cytoplasm is the key site for anaerobic processes in both prokaryotic and eukaryotic cells.
