Verified step by step guidance1
Understand the process of glycolysis: Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing energy and producing ATP and NADH.
Identify the location of glycolysis: Glycolysis occurs in the cytosol of eukaryotic cells, which is the fluid component of the cytoplasm.
Differentiate glycolysis from other metabolic processes: Unlike the citric acid cycle and oxidative phosphorylation, which occur in the mitochondria, glycolysis takes place in the cytosol.
Recognize the significance of glycolysis location: The cytosolic location allows glycolysis to be the first step in cellular respiration, accessible to glucose molecules entering the cell.
Review the options provided: Confirm that the cytosol is the correct answer by eliminating other options related to mitochondrial processes.
