So here you have a system, you have something -- and there’s plenty of that stuff in biology -- some substance giving an electron, and the electron tries to jump, and only when a molecule comes along that has the right vibration does the reaction happen, OK?
Siin on süsteem, sul on midagi... bioloogias on palju selliseid asju... mingi aine annab elektroni ja elektron proovib hüpata ja ainult siis, kui tuleb molekul, millel on õige võnkumine toimub reaktsioon.
