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 the cytosol (also called cytoplasm) as the fluid portion of the cell outside organelles, where many metabolic reactions take place.
Recognize that the nucleus contains genetic material and is not the site of glycolysis.
Know that the mitochondrial matrix and inner mitochondrial membrane are involved in later stages of cellular respiration, such as the Krebs cycle and electron transport chain, not glycolysis.
