Research Question How will the addition of 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

Determination of presence of protein in a variety of food substances by the use of Biuret Reagent Biol. 1040 Section 1005 Introduction The human body consumes carbohydrates‚ lipids‚ and proteins each day by eating a variety of foods. These foods are required for energy and human growth. Proteins are a diverse group of macromolecules with many different functions (Mbuthia‚ 2012). Many are structural components of bone‚ muscle‚ hair‚ tissue‚ etc. Others are enzymes that speed up cellular

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

some mold growing on the in the basement. My family hired me to find out why the mold is only growing the the basement. I did some background research to help me draw a hypothesis. Then drew a hypothesis and I came up with: If there is mold growing in the summer‚ then the change of weather would kill the mold in the cold. After I drew my hypothesis‚ I had to get testing my hypothesis. If then mold was thriving in the summer‚ then I had to put some in a cool environment. I scraped some mold that

On December 7‚ 2016 I started the fungi lab experiment. My goal throughout this procedure was to make evident the growth of fungi through a seven-day process I first had to go to the local grocery store to purchase all my substrates. The substrates include: One slice of potato (sample type A)‚ one slice of bread (sample type B)‚ one slice of kiwi fruit (sample type C)‚ a small slice of cake (sample type D)‚ and small cube size of avocado (sample type E). I then placed each item in a Ziploc bag; I

Anzia Yezierska’s Bread Givers attacks several social norms of both her traditional Polish homeland and the American life her protagonist has come to know. Clearly autobiographical‚ Bread Givers boldly questions why certain social and religious traditions continue throughout the centuries without the slightest consideration for an individual’s interests or desires. Sara’s traditional Jewish upbringing exposed her to a life dominated by patriarchal control; when she arrived in New York to seek
