D
Nucleus
Verified step by step guidance1
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 cytosol, which is the fluid portion of the cytoplasm outside the organelles in eukaryotic cells.
Recognize that the mitochondrial matrix and inner mitochondrial membrane are involved in later stages of cellular respiration, such as the Krebs cycle and oxidative phosphorylation, not glycolysis.
Note that the nucleus is primarily involved in storing genetic material and regulating gene expression, not in glycolytic reactions.
Therefore, conclude that the correct cellular location for glycolysis in eukaryotic cells is the cytosol (cytoplasm).
