You want molecular dynamics. They are simulations, not real images. But otoh (visible) light rays are "about as big" as a very large protein, so you can't image them. And because of computational expense they're slow motion by necessity, which is good because very, very complex enzyme interactions means ~2-3000 interactions per second. Example: [VIDEO]

An incredible story! Somewhere in [LINK] or [VIDEO] the narrator casually says "... and this is why we breathe oxygen ..."
