The metabolic pathway in which glucose is converted into pyruvate is called glycolysis. This process occurs in the cytoplasm (cytosol) of the cell, both in prokaryotes and eukaryotes.

Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm. It breaks down a molecule of glucose (a 6-carbon sugar) into two molecules of pyruvate (a 3-carbon molecule), producing a net gain of ATP and NADH.

Pyruvate then enters the mitochondria (in aerobic respiration) for further oxidation via the Krebs cycle and electron transport chain, or is converted to lactate or ethanol in anaerobic conditions (fermentation), also in the cytoplasm.
