Detailed explanation-1: -Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae ).

Detailed explanation-2: -There are two simple reasons why glycolysis occurs in the cytoplasm of the cell: The enzymes required for the glycolytic pathway are only found in the cytoplasm. A transport protein is required to move glucose across membranes.

Detailed explanation-3: -Glycolysis is the partial oxidation of glucose to produce pyruvate, which is then transferred to mitochondria for further oxidation. The cytosol is the fluid in which the cell’s organelles are located. No, glycolysis does not takes place in the mitochondria. It occurs in the cytosol.

Detailed explanation-4: -Glycolysis is found in the cytoplasm of virtually all kinds of aerobic/anaerobic cells.

Detailed explanation-5: -The mitochondria simply does not contain the enzymes inside it to perform glycolysis nor does it sufficiently have the membrane transport proteins to take glucose inside. This is the simple answer.
