8. Discussion questions.

9. Discussion Key Points
The yeast uses the sugar and warm water to grow. Warm water provides heat to accelerate the reaction .
As yeast grows it expands and gets bubbly. By being “bubbly” the yeast gives off carbon dioxide, the same gas that your body produces when you breathe, and the gas inflates the balloon. Yeast also produces ethanol.
Respiration provides organisms with the energy to do cellular work that helps them grow, function, and live.
People use yeast to bake because during fermentation, CO2 forms bubbles in the dough and expands it.
Since baking is done at high temperatures, yeast ultimately dies and nearly all the ethanol evaporates.
Ethanol fermentation is used to produce alcoholic beverages. People also use yeast fermentation to make ethanol for fuel.
