Detailed explanation-1: -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-2: -(i) In aerobic respiration, glycolysis occurs in the cytoplasm of a cell.

Detailed explanation-3: -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-4: -The glycolysis process starts in the cytoplasm of the cell. In this process, one molecule of glucose breaks down and gives rise to two molecules of pyruvate and two molecules of ATP. The end of glycolysis also takes place in the cell cytoplasm.
