Final answer:
The ultimate fate of the atoms in oxygen gas (O2) in cellular respiration is released as carbon dioxide. Glucose and oxygen are converted into carbon dioxide and water, with the carbon atoms from glucose being released as carbon dioxide. This process releases energy in the form of ATP. The correct option is b) Released as carbon dioxide
Step-by-step explanation:
The ultimate fate of the atoms in oxygen gas (O2) in cellular respiration is b) Released as carbon dioxide.
During cellular respiration, glucose, and oxygen are converted into carbon dioxide and water. The oxygen atoms from O2 combine with hydrogen to form water, while the carbon atoms from glucose are released as carbon dioxide. This process releases energy in the form of ATP, which can be used by the body's cells.
Cellular respiration occurs in four phases: glycolysis, the transition reaction, the citric acid cycle (also known as the Krebs cycle), and the electron transport chain. Throughout these phases, the glucose molecule is gradually broken down, releasing carbon dioxide as a byproduct. The correct option is b) Released as carbon dioxide
