Okay kiddo, let's talk about potential energy of proteins! So just like how people have energy that we get from food, proteins also have energy stored in them that they can use later. It's kind of like how you have energy stored in your toy box when you're not playing with your toys.
Now, this energy in proteins is stored in the way the protein is folded. You know how you fold your clothes and put them away in your drawers? Proteins fold themselves up like that too, and the way they fold can change how much energy they have stored.
Think of it like a rollercoaster. When the rollercoaster is at the top of a hill, it has a lot of potential energy because it's up high and has the potential to go really fast. If the rollercoaster starts going down the hill, it can use that potential energy to go really fast.
Proteins work sort of the same way. When they're folded up in a certain way, they have a lot of potential energy stored. If the protein needs energy to do something, like move around, it can use that stored energy to fuel that movement.
So in summary, proteins have potential energy stored in the way they are folded, and they can use that energy later on when they need it!
