Question: How is the rate of yeast fermentation of 7.5g of yeast affected by using different companies of yeast (Bakon Yeast Inc.‚ Lake States Yeast LLC‚ Lesaffre Yeast Corp‚ Red Star Yeast Company‚ and Minn-Dak Yeast CO Inc.)? Background Information: Yeast is a fungal microorganism that is used to manufacture mainly bread and beer. It reproduces rapidly. Fermentation is the process by which yeast takes in sugar and releases alcohol and carbon dioxide. Fermentation requires a mostly a damp

Alcohol and Driving Alcohol is a depressant that affects your vision‚ coordination‚ reaction time‚ multitasking ability‚ judgment‚ and decision-making. How can you drive safely if you can’t see‚ think‚ and move around well and react quickly? Alcohol affects your ability to identify dangerous situations and make good decisions when you know danger is ahead‚ and it slows your reaction time even if you do make a good decision. In addition‚ having alcohol in the body while you’re driving messes up your

Not only does it produce ATP‚ but also carbon dioxide (though decarboxylation)‚ NADH and FADH and in the case of some organisms‚ alcohol. Saccharomyces cerevisia‚ a bacterium commonly 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)

Investigation of Fermentation Introduction Introduction Yeast (Saccharomyces)is a single-celled microorganism in the Fungi family. It anaerobically respires sugars to produce ATP‚ as well as the waste products ethanol and carbon dioxide gas. This process is known as fermentation. There are various factors that affect the rate at which yeast respires. Aim To investigate the effect of concentration of table salt (sodium chloride) on the rate of fermentation of sucrose using yeast‚ measured in the

Effects of alcohol Cause and Effect Paper‚ Final Draft Causes and Effects of Alcoholism The causes and effects of alcoholism on society are far-reaching‚ tragic‚ and hard to deny. One of the many definitions of alcoholism is a primary‚ chronic disease with genetic and environmental factors influencing its development and manifestations. Harmful consequences from this dangerous addiction include the eventual inability of the addicted to be a productive member of society; liver and brain

investigation was to investigate the effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily increases when more substrate

Effects of Alcohol Alcohol can have some good benefits and then some bad ones‚ for example when you drink you can encounter yourself having a good time laughing and joking around with your friends‚ or you can find yourself angry wanting to argue and start fights with everybody. If you’re a “happy drunk” you probably don’t have bad alcoholism in your family‚ and you can control your drinking with the attitudes it may drag along. While on the other hand if you’re an “angry drunk” you may not be

Objective To investigate the effect of carbon dioxide concentration on the rate of photosynthesis Introduction Photosynthesis is a process that is essential for every living organism. Organic substances‚ such as glucose‚ are made from carbon dioxide and water by light energy from the sun. The light energy is absorbed by chlorophyll and converted to chemical energy. During the process‚ oxygen is released as a by-product. The rate of photosynthesis is affected by a few of factors‚ including

The Effect of the Concentration of Sulphuric Acid on the Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2

Evaluation Like any experiment‚ there were a number of potential errors during the procedure of the experiment. Errors could have arisen as a result of the uncertainties associated with the instruments I used to take measurements‚ and also as a result of errors associated with the actual method. Of course‚ due to the limitations of the procedure‚ they could not be eliminated completely‚ so I will explain what I did to reduce them to an acceptable level and how I could have improved my method to
