Students will also be able to expand and utilize scientific vocabulary words including: cellular respiration, fermentation, alcoholic fermentation, molecules One of the best-known types of fermentation is alcohol fermentation in which the overall chemical reaction is: C 6 H 12 O 6 (glucose) → 2CO 2 + 2CH 3 CH 2 OH (ethyl alcohol) Yeast, water, sucrose, and boiling the mixture did not create CO2 because the balloon did not inflate. lol it did not even take me 5 minutes at all! I get my most wanted eBook. When yeast cells carry out fermentation, they convert sugar molecules into ethyl alcohol (C 2H 5OH) and CO 2. Yeast + Water + Sucrose Yeast and water and sucrose will produce CO 2 because all the optimal elements are present to undergo fermentation. Procedure: Day 1.
