What is a product of cellular respiration?

  1. Oxygen

  2. Carbon dioxide

  3. Adenosine triphosphate

  4. Glucose

The correct answer is: Carbon dioxide

Cellular respiration is a process that occurs in cells, where glucose is converted into energy by breaking it down into smaller molecules. Oxygen is required for this process to take place, but it is not a product of cellular respiration. Carbon dioxide, on the other hand, is produced as a waste product and is exhaled out of the body. Adenosine triphosphate or ATP is the actual product of cellular respiration, as it is the energy molecule that is formed during this process. Glucose, while it is an important component for cellular respiration to occur, is not a product, but rather the source of energy that is broken down. Therefore, the correct answer is B Carbon dioxide.
