Recall that glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Understand that glycolysis occurs in the part of the cell where enzymes for this pathway are located and where glucose can be readily accessed.
Identify that glycolysis does not take place inside mitochondria (neither in the inner mitochondrial membrane nor the mitochondrial matrix), nor in the nucleus.
Recognize that glycolysis occurs in the cytosol, which is the fluid portion of the cytoplasm outside the organelles.
Therefore, the correct location for glycolysis is the cytosol (cytoplasm) of the cell.
