Recall the basic definition of glycolysis: it is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Understand that glycolysis is the first step in cellular respiration and does not require oxygen, so it occurs in a part of the cell where oxygen availability is not a limiting factor.
Identify the cellular compartments involved in metabolism: the cytosol (cytoplasm), the mitochondrial matrix, the inner mitochondrial membrane (cristae), and the nucleus.
Remember that glycolysis takes place in the cytosol (cytoplasm) because it involves enzymes that are freely floating in this fluid portion of the cell, not inside organelles like mitochondria or the nucleus.
Conclude that the correct location for glycolysis in a eukaryotic cell is the cytosol (cytoplasm), distinguishing it from later steps of cellular respiration that occur in mitochondria.
