I Photosynthesis and quantum randomness

[Atla2017]

Some studies suggest that during photosynthesis, electrons travel all possible paths simultaneously, and then always collapse at the reaction center.

My question is, doesn't that contradict quantum randomness? Shouldn't the location of the electron after the collapse be predictably random?

Welcome to the PF.

Can you post links to the studies you are referring to? That would probably help to get you better answers to your question. Thanks!

Thanks! Here are two (as far as I know this topic is now heavily researched):

I'm a layman, I guess I can't tell whether or not there's a mechanism involved here that can nearly perfectly "steer" the energy transport. Without such a mechanism it would seem to me to contradict quantum randomness.
