Yeast are unicellular eukaryotic organisms that have beenutilized for thousands of years to produce leavened (risen) breadand alcoholic beverages. To make leavened bread yeast are added tothe bread dough and once it is placed in a warm place, the yeastcause the bread to rise. Knowing what you do about glycolysis andthe fates of pyruvate, explain biochemically why the breadrises.
