yeast

/iːst/noun

A moist, yellowish foam formed when malt liquids ferment, used in brewing beer, raising bread dough, and in some medicines.

“Add the yeast to warm water and let the dough rise for an hour.”

Everyday baking vocabulary: bread recipes call for 'active dry' or 'fresh' yeast, and dough without it is 'unleavened'.
