Here's a breakdown:
* Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm of the cell.
* During glycolysis, a glucose molecule is broken down into two pyruvate molecules.
* This process also generates a small amount of ATP (energy) and NADH (an electron carrier).
The pyruvate molecules then move on to the next stage of cellular respiration, the Krebs cycle (also called the citric acid cycle), which takes place in the mitochondria.
