I’ve heard that nuclear fission and/or fusion only convert not even 1% of all the energy stored in an atom. How much energy is actually stored in an atom and is it technically possible to “extract” all of it?

How does the brain “know” to upregulate or downregulate receptors? And if we know the method of action, what is preventing us from developing a way to regulate specific receptors?
