Question

ariana garcia apontes practice r3 identify functions of animal cell parts select the part whose main job is to break down sugar and release energy that the cell can use. mitochondria chromosomes ribosome cytoplasm

Explanation:

To solve this, we analyze the functions of each cell part:

• Mitochondria: Known as the "powerhouse of the cell," it breaks down sugar (like glucose) through cellular respiration to release energy (ATP) that the cell can use.
• Chromosomes: Contain genetic material (DNA) and are involved in cell division and inheritance, not energy production.
• Ribosome: Involved in protein synthesis (translating mRNA into proteins), not energy breakdown.
• Cytoplasm: Is the jelly - like substance where cell organelles are suspended and chemical reactions occur, but it doesn't break down sugar for energy release.

So the part that breaks down sugar and releases energy is mitochondria.

Answer:

mitochondria
