ABSTRACT
If we want to know who is doing all the work in this house, we need to first know how work can be done at all. Of course, if we say that, we should wonder what “work” actually is. In this context one could say that work results in, from the viewpoint of the cell, useful outcomes — be they, for example, the manufacture of needed materials or locomotion. All of these outcomes have one thing in common: They require chemical reactions to take place.
