Answer:
carbon dioxide and water
Step-by-step explanation:
the most simple answer would be co2 and h20 since they are two molecular waste products formed as a result of cellular respiration, but ATP is also a product and is a molecule. So the question itself is faulty, since there are three products in cellular respiration.
It depends on how you learned it, but it says 2 so I would go with CO2 and H20.
