Mitochondrial matrix
C
Nucleus
D
Cytosol
Verified step by step guidance1
Recall the main stages of cellular respiration and where they occur within the eukaryotic cell. Glycolysis is the first step in glucose metabolism.
Understand that glycolysis involves the breakdown of glucose into pyruvate, producing ATP and NADH in the process.
Identify the cellular compartments involved in energy metabolism: the cytosol, mitochondrial matrix, and inner mitochondrial membrane.
Recognize that glycolysis takes place outside the mitochondria, specifically in the cytosol, which is the fluid portion of the cytoplasm.
Conclude that since glycolysis does not require mitochondria and occurs before pyruvate enters the mitochondria, the correct compartment is the cytosol.
