D
In the mitochondrial matrix
Verified step by step guidance1
Recall the primary location of glycolysis within eukaryotic cells. Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Understand that glycolysis occurs in the part of the cell where enzymes for this pathway are freely available and not enclosed by membranes.
Identify the cytosol as the fluid portion of the cytoplasm where many metabolic reactions take place, including glycolysis.
Contrast this with other cellular compartments such as the nucleus, rough endoplasmic reticulum, and mitochondrial matrix, which have different functions and are not the sites of glycolysis.
Conclude that glycolysis takes place in the cytosol because it is the site where the necessary enzymes and substrates are present and accessible for this pathway.
