In cellular respiration, the main products are typically ATP (adenosine triphosphate), carbon dioxide, and water. From the options you've provided, two additional products of cellular respiration are:
-
Water - This is produced during the electron transport chain stage of cellular respiration when oxygen acts as the final electron acceptor.
-
Carbon dioxide - This is produced during the Krebs cycle (also known as the citric acid cycle) as glucose is broken down.
The other options you provided, sugars and oxygen, are not products of cellular respiration. Instead, sugars (like glucose) are reactants, and oxygen is used in the process but is not produced as a result.
