Science Prac Introduction

Introduction The general purpose of this experiment is to test the resultant role of temperature on the natural process of yeast enzymes. Enzymes are proteins which act as a catalyst to bring about a ad hoc bio chemic substance reception (Ophardt, 2012). A catalyst is a subst score that increases the rate of a chemical reaction without itself undergoing all permanent chemical change (Clark, 2002). The reaction between an enzyme and its substrate takes place in a small part of the enzyme called the agile site where the substrate bind and undergo a chemical reaction (Ophardt, 2012). variant immaterial factors affect enzyme activity. An example of an external factor is temperature and as the temperature increases the rate of an enzyme- catalysed reaction increases due to more(prenominal) dynamical collisions (Worthington biochemical Corporation, 2012). If the temperature increase is great enough however, it potbelly lead to an enzyme- catalysed reaction to hang because th e enzyme may become denatured. This way some of the bonds that square up the active site may become broken and whence cause the enzyme- reaction to decrease (Effect of Temperature on Enzyme Activity). Alcoholic zymosis is a process from which sugars such(prenominal) as glucose are reborn by yeast into ethanol and carbon dioxide (YoBrew, 1999-2011).

Yeast contains an enzyme cognise as Zymase which is the catalyst for the fermentation process. The optimal temperature for Zymase activity is 35 degrees Celsius because the optimal temperature for enzyme activity in living organisms is 35 degrees Celsius and yeast is classified as a living organism (FreeFictionBooks.org , 2010). then it is hypothesised that enzyme activi! ty allow be greatest at 35 degrees. Below 35 degrees it is hypothesised that the enzyme activity leave be slight because of the rate of energetic collisions will still be increasing. above 35 degrees it is hypothesised that the enzyme activity will decrease because the rate of energetic collisions will be decreasing...If you motive to get a sufficient essay, order it on our website: OrderEssay.net
