Differences in End Products of Aerobic vs Anaerobic Respiration

During the process of cellular respiration, various metabolic pathways are involved in the breakdown of glucose to produce ATP. Anaerobic respiration, while less efficient than aerobic respiration, is critical for certain organisms. Consider a single-celled eukaryotic organism that can switch between aerobic and anaerobic respiration depending on the environment. Which of the following statements correctly identifies a key difference in the end products of these two types of respiration in this organism?
