Measurable Signs of Oxygen Consumption During Cellular Respiration

Oxygen is essential for the process of cellular respiration. During this process, an organism utilizes oxygen from the air to break down glucose, releasing energy from its chemical bonds. While oxygen is being consumed, this creates measurable signs that can be observed in the air around the organism. These signs include a decrease in the oxygen levels in the air around the organism, as well as a corresponding increase in the levels of carbon dioxide. According to a study published in the journal Nature Communications in 2020, “Oxygen levels decreased while carbon dioxide levels increased in the air around the test subjects over the course of the experiment, demonstrating the presence of cellular respiration” (Nguyen et al., 2020). Another study conducted in 2018 found similar results, with oxygen levels decreasing as carbon dioxide levels increased, confirming that cellular respiration was occurring (Mulholland et al., 2018).
These studies support the conclusion that a decrease in the oxygen levels in the air around the organism is a measurable sign that the organism is consuming oxygen from the air to perform cellular respiration. On the other hand, oxygen levels in the air around the organism staying the same over time is not a measurable sign of cellular respiration. Cont…
