Here's why:
* Mitochondria are the "powerhouses" of the cell: They are responsible for generating ATP (adenosine triphosphate), the cell's primary energy currency.
* Cellular respiration occurs in four main stages:
* Glycolysis: Occurs in the cytoplasm.
* Pyruvate oxidation: Occurs in the mitochondrial matrix.
* Citric acid cycle (Krebs cycle): Occurs in the mitochondrial matrix.
* Electron transport chain and oxidative phosphorylation: Occurs on the inner mitochondrial membrane.
While glycolysis begins in the cytoplasm, the majority of cellular respiration relies on the intricate structure of the mitochondrion.
