Effect of Sugar Type on Rate of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast with

The use of yeast as a food dates all the way back to the Ancient Egyptians. Note that unlike the yeast used to leaven bread‚ nutritional yeast is inactive. It has been deactivated so that it cannot be used to make bread rise or convert sugar into alcohol. It is also different from brewer’s yeast‚ though the two are strains of the same fungus. The main difference is the source. As its name suggests‚ brewer’s yeast is a product of the brewing industry; it is typically bitter because it is grown

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

dioxide to make sugars. 2. What happens to food energy during photosynthesis? During cellular respiration? In Photosynthesis light energy along with carbon dioxide are used to make molecules or (food energy). In Cellular Respiration food energy is broken down to form ATP. 3. Why is photosynthesis important to you? Photosynthesis is important because plants‚ bacteria‚ and small animals use photosynthesis to eat. Photosynthesis converts light energy into sugars and other proteins

Testing for reducing sugars‚ non-reducing sugars‚ starch‚ lipids and proteins in unknown substances: Our aim: was to find out which substances from our five samples have reducing sugars present to determine what they may be for example; they could be monosacchrides or disaccharides. This was carried out by using Benedict’s test. To find out which substances from our five samples were non-reducing sugars‚ since some disaccharides are reducing sugars and this would be carried out by using Benedict’s

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical oxidation

Diabetes is a disorder of the body’s sugar-regulation abilities. Most of the time it goes undiagnosed because the symptoms are not very clear. There are many symptoms‚ but they don’t appear in all cases. The symptoms include frequent urination (polyuria)‚ which occurs because of the high blood sugar levels. High blood sugar levels result in an overflow of glucose from the kidneys‚ carrying the fluid along with it. Because there is a constant loss of body fluid through urination there is a constant
