The Effect of Temperature on Yeast Enzymes Aim: The aim of this experiment is to find out the effect of different temperatures on yeast enzymes using a water bath, thermometer, etc. Background: Yeast is a type of fungi or mushroom. It is a single-celled micro-organism and is used in making bread rise as well as alcohol, or ethanol, making. Another method of using yeast to make alcohol is fermentation. The chemical follows: Glucose-------> 2 ethanol + 2 carbon dioxide + heat C6H12O6 (glucose) ›2C2H5OH + 2CO2 The yeast enzymes are packed with enzymes called zymase. Yeast reproduces asexually. During asexual reproduction, a new bud grows out of the parent yeast when the condition is right, then, after the bud reaches an adult size, it separates from the parent yeast. Under low nutrient conditions yeasts that are capable of sexual reproduction will form ascospores. Yeasts that are not capable of going through the full sexual cycle...
