Electrons travel like urban commuters
After 15 years of research, chemists from Duke University have found that electrons travel through proteins like urban commuters. Like ourselves, these electrons usually find their way through proteins by using the fastest routes, the equivalent of the subway for us. And like us, they also used sometimes alternate routes, like when we take a cab, a bus, or decide to walk. Even if you're not convinced right now, these electron transfers inside proteins are very important because they are part of many processes essential for life, such as harvesting light in photosynthesis in plant cells and generating energy in animal cells.
