Many breads arc made by adding yeast to dough, causing the dough to
rise. Yeast is a type of microorganism that produces the catalyst zymase,
which converts glucose, C6H12O6' to
ethanol and carbon dioxide gas. The balanced equation for this reaction
is shown below.
C2H5OH(aq) + 2

Describe how the catalyst, zymase, speeds up this reaction. [I]
|Answer--> lowers the activation energy
Determine the total mass of ethanol produced
when 270. grams of glucose reacts completely to form ethanol and 132
grams of carbon dioxide.
|Answer--> 138g (270g-132g=138g)
