What happens to the oxygen that is metabolized within the
mitochondria?
a. The oxygen is converted to CO2. b. The oxygen is incorporated
into organic molecules during cellular metabolism. c. The oxygen is
combined with hydrogen to form water. d. The oxygen acts as a
coenzyme in the production of ATP. e. The oxygen is converted to
CO2 and is combined with hydrogen to form water
Can you explain the answer please.
Answer
Oxygen is utilised in the final stage of ATP formation at the
complex V of the Electron transport chain that occurs in the inter
membranous space of the mitochondria. Oxygen acts as a great
electron acceptor. As the ions within the space move into the
matrix, oxygen combines with hydronium and accept electron from
complex leading to formation of water.
hence c is correct.
