Oxygen utilization is a research area that focuses on the various ways in which organisms use and consume oxygen for various metabolic processes. This includes studying how oxygen is taken up by cells, transported through the body, and utilized during processes such as respiration and energy production. Researchers in this field may investigate how oxygen levels affect overall metabolism, performance, and health. Additionally, they may explore how oxygen utilization differs between different organisms or under varying environmental conditions. Understanding oxygen utilization is important for various fields such as physiology, exercise science, and environmental science.
