Answer:
Mitochondria of the cell.
Step-by-step explanation:
Cellular respiration is defined as the process of oxidizing organic molecules like glucose, to carbon dioxide and water.
C6H12O6 + 6O2 + 6H2O → 12H2O + 6CO2
The energy released is trapped in the form of ATP which is used by all the energy-consuming activities of the cell.
Mitochondria is an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It also provides energy for these processes.
