A
Nucleus

C
Mitochondrial matrix
D
Inner mitochondrial membrane
Verified step by step guidance1
Understand that glycolysis is the metabolic pathway that breaks down glucose into pyruvate, producing ATP and NADH in the process.
Recall that glycolysis does not require oxygen and occurs in the part of the cell where enzymes and substrates for this pathway are freely available.
Identify the cellular compartments listed: nucleus, cytosol (cytoplasm), mitochondrial matrix, and inner mitochondrial membrane.
Recognize that the mitochondrial matrix and inner mitochondrial membrane are involved in aerobic respiration steps after glycolysis, such as the Krebs cycle and electron transport chain.
Conclude that glycolysis primarily occurs in the cytosol (cytoplasm) of eukaryotic cells, where the necessary enzymes and substrates are located.
