Question

N the cell, which organelle has the function of using oxygen in the breakdown of glucose, releasing energy and carbon dioxide?

Answer 1

Answer: The correct answer is C) Mitochondria.

Aerobic cellular respiration is a metabolic process in which glucose is oxidized to release large amount of energy in the form of ATP ( adenosine triphosphate) that is utilized for various cellular activities.

It occurs in three phases that is Glycolysis ( occurs in cytoplasm of cell), Kreb cycle ( occurs in mitochondrial matrix), and Electron transport chain ( in the inner mitochondrial membrane).

Mitochondia is the organelle that utilizes oxygen as final electron acceptor in the electron transport chain to release energy and CO₂ ( carbon dioxide).

Answer 2

Mitochondria. This is where cellular respiration takes place.
