D
Cytosol (cytoplasm)
Verified step by step guidance1
Recall the process of glycolysis and where it occurs within eukaryotic cells. Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH.
Understand that glycolysis does not require oxygen and occurs outside the mitochondria, unlike other stages of cellular respiration such as the Krebs cycle and oxidative phosphorylation.
Identify the cellular compartments listed: mitochondrial matrix, nucleus, inner mitochondrial membrane, and cytosol (cytoplasm).
Know that the mitochondrial matrix and inner mitochondrial membrane are involved in later stages of cellular respiration, while the nucleus is primarily for genetic material storage and transcription.
Conclude that glycolysis takes place in the cytosol (cytoplasm), the fluid portion of the cell outside organelles, where enzymes for glycolysis are located.
