Recall the process of glycolysis, which is the breakdown of glucose into pyruvate, producing ATP and NADH in the process.
Understand that glycolysis is the first step in cellular respiration and occurs independently of oxygen availability.
Identify the location within the eukaryotic cell where glycolysis takes place by considering where enzymes for this pathway are found.
Recognize that glycolysis occurs in the cytosol (cytoplasm) of the cell, not inside the mitochondria or nucleus.
Confirm that other stages of cellular respiration, such as the Krebs cycle and oxidative phosphorylation, occur in the mitochondrial matrix and inner mitochondrial membrane, respectively, distinguishing them from glycolysis.
