Where is the Krebs cycle located?

In eukaryotic cells, the Krebs cycle is located in the mitochondrial matrix, the innermost part of the mitochondria. This location enables efficient processing of acetyl-CoA and immediate transfer of generated high-energy electrons to the adjacent electron transport chain in the inner mitochondrial membrane. In prokaryotic cells, where mitochondria are absent, the Krebs cycle takes place in the cytoplasm.
