Bioenergetics

Bioenergetics is like the way our body uses food for energy. Just like how cars need gas to move, our body needs food to do things like run, jump, and even breathe properly.

When we eat food, our body breaks it down into smaller pieces called molecules. This process is called digestion. The molecules that we get from our food go into our blood and travel all around our body.

Inside our body, there are tiny things called cells, and every cell needs energy to do things. That's where bioenergetics comes in. The molecules from our food go into our cells and are turned into a type of energy that our cells can use, called ATP. It's kind of like the battery that powers our cells.

So when we need to do something like run or jump, our cells use the ATP energy to help our muscles move. But just like how a car runs out of gas eventually, our cells eventually run out of ATP too. But don't worry! Our body knows how to make more ATP from the food we eat, so we can keep moving and doing all the things we love.

So in simple terms, bioenergetics is how our body uses food to make energy that our cells need to do things like move and breathe.
