What is an analogy for Mitochondria?

Mitochondria

The Mitochondria is the powerhouse of the cell. It generates energy to make things happen.

Powerhouse

It is known as the "Powerhouse" of a cell.

The mitochondria is the organelle of the cell that breaks down food molecules to make ATP.

It basically gives the cell energy.

One analogy I think of is mitochondria are to glucose and oxygen as solar panels are to sunlight. Both utilize the energy in other sources to produce a type of energy we can use.

You can also represents mitochondria with an electrical supply of a company or fuel feeding a boiler.
