Biology

In prokaryotic cells, cellular respiration takes place in the cytoplasm.

Prokaryotic cells lack membrane - bound organelles such as mitochondria. In prokaryotes, the entire process of cellular respiration occurs in the cytoplasm. Glycolysis, which is the first step of cellular respiration, occurs in the cytoplasm of all cells (both prokaryotic and eukaryotic). In addition, the enzymes for the subsequent steps of cellular respiration (the Krebs cycle and electron transport chain in eukaryotes) are also located in the cytoplasm or associated with the cell membrane of prokaryotes.
