Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.

Each stage produces ATP, but only the first stage occurs in the cytoplasm.

Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.

ATP is produced from each astep of cellular respiration. So the correct option is option C.
