In the human body, where does glycolysis take place?
A

Inner mitochondrial membrane
C
Cytosol (cytoplasm) of cells
D
Cell nucleus
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 occurs in the part of the cell where enzymes for this pathway are located and where glucose can be readily accessed.
Identify that the mitochondrial matrix and inner mitochondrial membrane are involved in later stages of cellular respiration, such as the Krebs cycle and electron transport chain, not glycolysis.
Recognize that the cell nucleus is primarily involved in storing genetic material and is not the site of glycolysis.
Conclude that glycolysis takes place in the cytosol (cytoplasm) of cells, where the necessary enzymes and substrates are present for this pathway to occur.
