In eukaryotic cells, where does glycolysis primarily occur?
A
Mitochondrial matrix
B
Nucleus
C
Inner mitochondrial membrane
D
Cytosol (cytoplasm)
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 for this pathway are located.
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 (like the Krebs cycle and electron transport chain), not glycolysis.
Recognize that glycolysis primarily takes place in the cytosol (cytoplasm) of eukaryotic cells, where the necessary enzymes and substrates are freely available.
