Verified step by step guidance1
Recall the 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 a cytoplasmic process, meaning it occurs outside the mitochondria in eukaryotic cells.
Identify the cytosol (also called cytoplasm) as the fluid portion of the cell where many metabolic reactions take place, including glycolysis.
Recognize 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.
Conclude that glycolysis takes place in the cytosol of eukaryotic cells, not inside the mitochondria or nucleus.
