Answer: The correct answer is- The mitochondrion.
Cellular respiration is a process of oxidation of food molecule ( like glucose) so as to form carbon dioxide, water, and large amount of energy in the form of ATP ( adenosine triphosphate). It can be of two types that is aerobic ( that occurs in eukaryotes) and anaerobic ( in prokryotes) cellular respiration.
The three phases of aerobic cellular respiration are - Glycolysis ( in cytpoplasm), Kreb cycle ( mitochondrial matrix), and electron transport chain ( in the inner mitochondril membrane)
In eukaryotes, maximum amount of energy is formed within mitochondria.
Thus, mitochondria is the location within cell where cellular respiration occurs.
In case of prokaryotes ( like bacteria), cellular respiration takes place in cytoplasm and cell membrane ( as they lack mitochondria).
