What is FADH₂?

FADH₂ is like a tiny battery that helps our bodies make energy from food.

Imagine you're playing with a toy car that needs batteries to move. When you put in fresh batteries, the car zooms around. FADH₂ is kind of like those batteries, it gives power to something important inside your body called mitochondria, which are like little factories that make energy for your cells.

FADH₂ is made when your body breaks down food, especially things like fats and sugars. It's like when you tear apart a big snack into smaller pieces so it’s easier to eat.

Once FADH₂ is made, it goes to the mitochondria and helps create something called ATP, which is the main energy coin used by all your cells. Think of ATP as the money that lets your muscles move, your brain think, and your heart beat, just like how a toy car needs batteries to go.

So FADH₂ is like a helper that gives power to the tiny factories in your body so they can make the energy you need to run, play, and grow.
