    There are more than one forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide

    Cervisiae<br><br><b>Description</b> - Yeast is a unicellular organism that lacks chloroplasts. They are so small that it can ’t be seen by the naked eye and they are so small that it would take 4000 of them lined up side by side to measure an inch. <br><br><b>Habitat</b> - Yeast lives on and is nourished by dead or living plant or animal matter. The ideal conditions of yeast is high humidity and temperature‚ plus lots of food. In bad conditions though the yeast produces a second cell wall for protection and the yeast contents

    Ms. Lunsford Honors Chemistry 12/6/2011 Abstract Yeast is widely used for making bread‚ beer‚ and wine. People all over the world drink and eat those products. This projects looks at which fruit juice with a higher percentage of sugar will produce more fermentation. The original purpose of this experiment was to determine the amount of fermentation of 3 different fruit juices after adding a certain amount of yeast. By measuring the type of fruit juice (independent variable) the amount

    of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that are directly absorbed into the bloodstream during digestion.
