Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator of fermentation. But our

Factors Affecting Fermentation of Glucose by Yeast Introduction: Fermentation is anaerobic respiration whereby food is altered into more simple compounds and energy in the form of chemicals is produced‚ an example being adenosine triphosphate (biology-online.org/dictionary/Fermentation). All this occurs with the lack of atmospheric oxygen. At the end of the day alcohol and carbon dioxide are the end products when yeast is used in the fermentation procedure. But end products like acetic acid

THE PROCESS OF FERMENTATION THROUGH DIFFERENT KINDS OF SUGARS In order to produce ethyl alcohol fermentation‚ we had to determine what sugars used‚ such as glucose (a single sugar) sucrose (table sugar) and lactose (milk sugar) will react with yeast to produce ethyl alcohol fermentation. My hypothesis is that the sugar lactose would produce the highest amount of bubbles and ferment. INTRODUCTION: The significance of fermentation is a lengthy process that has been practiced by humankind

the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it will cause self- destruction or death in the microorganism of the yeast. If the antimicrobial activities in Convallaria majalis’s inhibit yeast fermentation‚ then the amount of CO2 evolved in the fermentation process will slowly decease or no CO2 will be formed. However‚ the results

How to find success in IB Biology The International Baccalaureate program offers many classes in the vast majority of SL and HL credits with the program and does so with the science section of the program. There are many different HL science classes that can be taken in IB but here at Edison‚ there are only two classes offered once you become a senior who is looking to take an HL science class. The two choices are HL Physics and HL Biology. Both are arguably the toughest IB classes offered at Edison
