Image you can trace a particular oxygen atom in an oxygen molecule you have just inhaled. Describe all possible molecules this oxygen atom may end up with.
Ans. Oxygen we inhale is used as terminal electron acceptor in electron transport system (ETC) and water is formed. Hence, water produced as a result of cellular respiration contains oxygen we inhale. Oxidation of glucose involves the production of CO2 as a biproduct and this CO2 produced is resulted with the utilization of oxygen we inhale and hence oxygen we inhale end up in CO2 during aerobic respiration. Oxygen we inhale combines with haemoglobin to form oxyhaemoglobin.
