different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine. Usually iodine has a orange-yellow color‚ but iodine

Significance of the Enlightenment in the development of the scientific method of inquiry The Enlightenment‚ Siècle des Lumières in French‚ usually referred to a series of ideology and culture movements during 1750s-1850s. There were many spheres of knowledge contained in these movements‚ such as: natural science‚ philosophy‚ ethics‚ politics‚ economics‚ literature and education. However‚ the Enlightenment did not originate from France; it was the extension of the Renaissance in Italy in the 14th

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was tested by having a chamber with quadrants that contain the culture‚ a hemacytometer‚ was used to carry out this experiment. After the data was collected from using the hemacytometer‚ the results of the difference between the two cultures was to be determined through a t-test. As the test was conducted‚ the study shows that the difference between lacking an antibiotic and containing one is not different. An antibiotic

Synthesis of Butyl Benzoate Using Phase Transfer Catalysis The objective of the experiment is to synthesize the butly benzoate by nucleophilic substitution and characterize it by IR spectroscopy. The percent yield of the final product is determined after the synthesis. Procedures: 2.0 mL of 1-bromobutane‚ 3.0 g of sodium benzoate‚ 5.0 mL of water‚ 4 drops of Aliquat 336‚ and a boiling stone were placed in a 50mL round-bottomed flask. The reaction mixture was refluxed for 1 hour and the flask
