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

Mitochondria breaks down sugar molecules that supply energy to the cell

Explanation:

Process of breaking down of the sugar molecule in order to produce energy is known "cellular respiration". All this activity takes place in the mitochondria. It is also referred as the energy source of cell. It utilises the food to produce ATP, that produces energy.

Mitochondria has its own ribosomes and DNA. They can prepare their protein without being dependent upon the cell. Mitochondria multiplies through fission. Glucose is broken down to pyruvate in cell cytoplasm.This   pyruvate when enters into mitochondria is converted to water and carbon dioxide.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

allowed for the prediction of the properties of missing elements.
