Used to define and identify geological times.<span />
I’m pretty sure it’s the first option, if not I am so sorry.
<span>The answer is (1) releases energy. In the cells of the human body, oxygen molecules are used directly in a process of cellular respiration during which energy is released. In cellular respiration, glucose and oxygen yield carbon dioxide and water and energy is released in the form of adenosine triphosphate: C₆H₁₂O₆ (glucose) + O₂ (oxygen) → H₂O (water) + CO₂ (carbon dioxide) + ATP (adenosine triphosphate).</span>
Answer:
D. respiration
Explanation:
It is basically a process that takes place in the cells of organisms. It converts chemical energy from oxygen molecules or even nutrients into ATP.
Hope this helped!
