Carbon dioxide (CO₂) is produced during two stages of cellular respiration:

1. Pyruvate Oxidation: This is the step between glycolysis and the citric acid cycle. In this process, each pyruvate molecule is oxidized and decarboxylated, which means one carbon atom is removed from each pyruvate, forming a molecule of CO₂.

2. Citric Acid Cycle (also known as the Krebs cycle or TCA cycle): In this cycle, the remaining two carbon atoms from the original glucose molecule are also removed as CO₂. This happens during the decarboxylation of isocitrate to alpha-ketoglutarate and the decarboxylation of alpha-ketoglutarate to succinyl CoA.

So, the correct answer choices are Pyruvate Oxidation and Citric Acid Cycle.
