Recall that glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Understand that glycolysis does not require oxygen and occurs in the part of the cell where enzymes and substrates for this pathway are freely available.
Identify the cellular compartments listed: nucleus, cytosol (cytoplasm), inner mitochondrial membrane, and mitochondrial matrix.
Know that the nucleus is primarily involved in DNA storage and RNA synthesis, not glycolysis.
Recognize that glycolysis takes place in the cytosol (cytoplasm), which is the fluid portion of the cell outside organelles, where the glycolytic enzymes are located.
