Citric acid cycle priming

It is notoriously easier to destroy than to build. The methods by which the cell breaks down its constituents are indeed ingenious, but their prime purpose is simply to provide systems for pulling molecules apart and releasing their potential energy with the minimum of fuss and bother. The molecules are knocked about, pushed and pulled into convenient shapes, like limousines in a breaker s yard, with scant ceremony and little respect for what they once were, until at last all that is left of them can be pounded out through the citric acid cycle and dumped as carbon dioxide.
