    An experiment to demonstrate the effect of temperature on fermentation by yeast The purpose of this laboratory is to observe how temperature affects the metabolism of Grape juice by visibly noting the volume changes of identical food mixes containing yeast at different temperatures. Background Information If yeast is added to a liquid containing sugar and other nutrients‚ kept at an appropriate temperature (and deprived of oxygen)‚ it will turn the sugars into ethanol (alcohol) and carbon

    of our investigation is to find out whether the use of different sugar isomers with yeast‚ will affect the rate at which the yeast respires at. The sugars to be tested are fructose‚ galactose‚ glucose‚ lactose and sucrose. Their effects on the respiration rate of yeast to be observed through the measurement (cm3) of the displaced water‚ which will tell us how much CO2 has been respired over 2 minutes. To compare the effects an average will be calculated for each and a result will be drawn from which

    known as yeast‚ is used in various aspects of life‚ from winemaking to baking. It respires both anaerobically and aerobically to produce CO2 and alcohol in a process known as fermentation (Barrio‚ 2009). It does this by breaking down the sugars (in the process outlined in figure 1) in the mitochondria (see figure 2). There are various factors

    The graph shows that the respiration rate does increase as the yeast concentration rises‚ but levels off and eventually reached its saturation point‚ or decline‚ which occurs at 8.5g. This decline may occur because there are too many yeast molecules in comparison to the glucose‚ which may lead to yeast cells hindering a collision thus lessening the reaction. The respiration rate increases as more yeast is added because it gives more opportunities for molecular collisions and so the amount of successful

    the lab study that we are going to conduct I choose Yeast as my organism. First off Yeast is a microscopic fungus consisting of single oval cells that reproduce by budding or fission (is the splitting of an atom)‚ and capable of converting sugar into alcohol and carbon dioxide. When making your own bread‚ you can buy yeast in the grocery store. The yeast contains little brown grains that will carry out cellular respiration and grow when put in water with sugar. In order to conduct the lab the specific
