Mitochondrion

Real World Example

Imagine trying to power your smartphone, but all you have is a bulky car battery. Just as you need a way to convert the energy stored in that car battery into a form that your smartphone can use, cells need mitochondria to convert the energy in food molecules into a usable form. The mitochondrion acts like an adapter, transforming the chemical energy in food into ATP, which is like the smartphone's battery, providing the immediate and usable energy needed for cellular functions.
