Which organelle breaks down sugar molecules that supply energy to the cell

Mitochondrion

Definition: Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule). Meaning, Mitochondria is referred to as the power house of the cell because it handles cellular respiration of the cell, which involves breaking down of sugar molecules to form energy
