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

Mitochondria

Explanation:

In eukaryotic cells, mitochondria are the organelles whose function is the synthesis of the energy required for the metabolic functions of all organisms. In the mitochondrial matrix, the 4 steps of cellular respiration occur. This is important, since it will generate ATP at the expense of glucose, fatty acids and amino acids.
