nature's catalyst, speeding reactions millions of times without ever using itself up
means A protein that speeds up a specific biochemical reaction in living things, making it happen far faster while emerging unchanged to do it again.
from From German Enzym, coined in 1878 by physiologist Wilhelm Kühne, built from Greek roots: en- 'in' and zyme 'leaven' or 'yeast' — literally 'in the leaven.' The choice was pointed: scientists had long argued over what made bread rise and dough ferment, and 'enzyme' named the working agent found inside the yeast rather than the yeast itself. That same zyme gives us 'zymurgy,' the craft of brewing and fermentation.
