Once yeast is activated it is living.
To be activated, yeast needs warmth, water, and sugar.
The smell you get from fermented dough is from the Yeast reacting with the fermentable sugars and causing carbon dioxide to be given off. The smell can vary, getting stronger the longer the dough is allowed to rise.
Yeast is activated by sprinkling it over warm water (100 - 109 degrees F) with a small amount of sugar. It should sit until foamy, about 5 minutes.
Yes, yeast (even dried yeast) is a living organism and if it is not used/activated in a given time period the yeast cells will die and the yeast will not work in baking/brewing.
a yeast infection is most of the time itchy and sometimes smelly, if you are reallym intune to your body you can tell the difference between your regular smell and the yeast smell.
Yeast will respire the sugar causing the yeast to give off Carbon Dioxide.
yes, it is not activated until you add water and sugar
The purpose of yeast is to raise the dough when it is cooked. If yeast is not working then, you'll end up with unrisen or flat bread.
Yeast is a living organism much like a mold.

Incubating yeast before using it in a recipe allows it to become activated and begin fermenting, which is necessary for leavening the dough or achieving the desired flavors in the final product. The incubation process helps to ensure that the yeast is alive and healthy, leading to better fermentation and rising of the dough.
