Identify the organelle responsible for energy conversion in the cell. The question asks which organelle converts energy stored in food molecules into ATP, the energy currency of the cell.
Recall that ATP (adenosine triphosphate) is produced during cellular respiration, a process that breaks down food molecules like glucose to release energy.
Understand that cellular respiration primarily occurs in the mitochondrion, which has specialized structures (like the inner membrane) to facilitate this energy conversion.
Eliminate other options: the Golgi apparatus is involved in protein modification and sorting, lysosomes digest cellular waste, and ribosomes synthesize proteins.
Conclude that the mitochondrion is the organelle that converts energy stored in food molecules into ATP during cellular respiration.
