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: -Glycolysis occurs in the cytoplasm where one 6 carbon molecule of glucose is oxidized to generate two 3 carbon molecules of pyruvate. The fate of pyruvate depends on the presence or absence of mitochondria and oxygen in the cells.

Detailed explanation-3: -Glycolysis is the process by which glucose is broken down within the cytoplasm of a cell to form pyruvate. Under aerobic conditions, pyruvate can diffuse into mitochondria, where it enters the citric acid cycle and generates reducing equivalents in the form of NADH and FADH2.

Detailed explanation-4: -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-5: -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.
