C
Golgi apparatus lumen
D
Cytosol
Verified step by step guidance1
Recall the basic cellular compartments involved in metabolism: mitochondria (including matrix and inner membrane), cytosol, and organelles like the Golgi apparatus.
Understand that glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Recognize that glycolysis occurs in the cytosol, which is the fluid portion of the cytoplasm outside organelles, allowing enzymes involved in glycolysis to function there.
Note that other metabolic processes, such as the citric acid cycle and oxidative phosphorylation, occur inside mitochondria, but glycolysis itself is cytosolic.
Therefore, identify the cytosol as the correct cellular compartment where glycolysis primarily takes place.
