molecule

Most of the molecules that are here on Earth have been here for billions of years.

They work with molecules, they work with atoms, they work with electrons.

But sometimes, your cells need molecules to move toward an area where there’s already a lot of them.

Molecules that are full of potential energy, like a coiled spring, get released to do work in our cells and our bodies more broadly.

In animals with lungs, the oxygen molecules automatically move from where there’s a bunch of oxygen, to where there isn’t much—the bloodstream.

In this current moment, we have evidence of complex molecules on Mars.
