PH: I will make sure that the pH is stable (constant) and only the temperature varies this is to be done by using buffer in every test tube so as to maintain pH balance for each beetroot sample and insure that pH does not become a variable. PH is important for maintaining the integrity of the cell membrane as integral proteins can denature upon change in pH. Also‚ presumably the buffer will have the right concentrations of salt or electrolyte’s (ion such as Na‚ K‚ Ca‚

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

and determine the optimum temperature and pH of the amylase. EXPERIMENTAL In the enzymatic activity of salivary amylase‚ 1ml saliva‚ 9ml distilled water and 30ml of 0.5% NaCl made up the enzyme solution. One percent starch in phosphate buffer pH 6.7 was the buffered starch. The experiment was comprised of two parts. For the first part (effect of temperature)‚ 2 ml of the enzyme solution was placed in a large test tube and labelled as 4℃. In a separate large test tube‚ 2 ml of the buffered

Acids‚ Bases‚ and Buffers Introduction: The pH scale is used to determine how acidic or basic a solution is‚ ranging from 1-14. The most acidic of all acids are at a pH level of 1 and the most basic of all bases are at 14. The neutral pH level is 7‚ which is what drinking water is. The pH level is determined by the amount of H+ ions present in a solution‚ and the more H+ ions there are the more acidic it is‚ and the lack of these ions results in more basic solutions. One distinguishing feature

For Experiment 5‚ a mixed solution of ONPG solution and Sodium phosphate buffer pH 7.3 is incubate at different temperature‚ 25‚ 40‚ 50‚ 60 and 70 °C. The mixed solution is then incubated for another 10 minutes after the enzyme is added in their respective temperature. Then‚ using spectrophotometer‚ the absorbance in the mixed

From a positive intention to a partial disaster‚ eight words that describe the Georgia Colony of England perfectly. Inspired by his friend who died in prison from debt‚ James Oglethorpe‚ co-creator of the colony‚ intended the colony to be a way for debtors from prison to pay their debts off to England. However‚ King George and the England Parliament disagree with the idea of having hundreds of debtors to be sent over sea‚ towards a land very unknown to England. King George actually liked the idea

which could be due to surface air denaturation of the protein. Buffer solution was used to renature the protein. However‚ renaturation did not happen 100%. Using an affinity column‚ LDH was purified away from contaminant proteins. The 60% cut was loaded on to a column filled with AMP-agarose beads. There were two classes of contaminant proteins present‚ AMP binding and non-AMP binding proteins. First‚ a potassium phosphate buffer solution was used to rinse the column in order to make sure all
