Cellular respiration consists of three stages: Glycolysis, the Citric Acid Cycle, and the Electron Transport Chain.
Glycolysis: The first stage of cellular respiration where glucose is broken down into pyruvate in the cytoplasm, producing 2 ATP molecules.
Citric Acid Cycle: Also known as the Krebs Cycle, it is a series of chemical reactions in the mitochondria that further break down pyruvate.
Electron Transport Chain: In this stage, electrons pass through proteins, lose energy, and ATP is formed through oxidative phosphorylation.
