Stesha Britman October 17, 2007 Biology Lab Is Yeast Alive? Abstract: The object of this experiment was to understand how cellular respiration represents cellular capability. If there is no sugar, then the yeast will not grow. We put sugar in some mixtures of yeast and water but not in others to see which ones filled up the balloons that we attached. Only the mixtures with the sugar produced gas to fill up balloons. My hypothesis was correct because without a food the organism can not produce any products. I learn that yeast is a living fungus. Introduction: Yeasts maybe plain fungi, but they have numerous vital environmental and profitable roles in our world. Yeasts grow in all regions of the globe including the kitchens of millions of houses where they are utilized in the making of food and beverages. Some types of yeasts can lead to infection in animals and plants, including people. While most yeast live in soil, on plant surfaces and on decaying matter. Some yeasts are significant model organisms in scientific experiments. The purpose of this lab is to study the effects of glucose concentration on the rate of cellular respiration in yeast cells. Also, to identify reactants and products of cellular metabolism. I think if there is no sugar for the yeast to feed on then it will not grow and expand, releasing CO2 gas.
