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: -Answer and Explanation: 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 a cytoplasmic pathway which breaks down glucose into two three-carbon compounds and generates energy. Glucose is trapped by phosphorylation, with the help of the enzyme hexokinase. Adenosine triphosphate (ATP) is used in this reaction and the product, glucose-6-P, inhibits hexokinase.
