Verified step by step guidance
1
Understand that glycolysis is the first step in cellular respiration, where glucose is broken down into pyruvate, producing ATP and NADH.
Recall that glycolysis is a process that occurs in the cytosol of the cell, which is the liquid found inside cells, excluding the organelles.
Differentiate glycolysis from other stages of cellular respiration, such as the Krebs cycle and oxidative phosphorylation, which occur in the mitochondria.
Recognize that the mitochondrion is involved in later stages of cellular respiration, but glycolysis specifically takes place in the cytosol.
Conclude that the reactions of glycolysis occur in the cytosol of a eukaryotic cell, not in any part of the mitochondrion.
