Question: Can a rubber balloon be inflated by yeast and sugar? Background information: Yeasts are unicellular organisms also known as the mircro-organisms that makes bread rise. In the absence of oxygen gas, yeasts carry out fermentation and convert sugar (glucose) into another organic compound (lactic acid or ethyl alcohol) and carbon dioxide gas which create the bubbles in bread and cause the bread to rise. Fermentation is an example of a chemical change that forms a gas. During the process of fermentation, the sugar molecules brake down to release the energy yeasts use to live and carbon dioxide is released as a waste product. Yeast cells provide enzymes (biological catalysts) that let fermentation to take place. Yeasts are also used to
