  • The Effect Of Ph Level On Starch Digestion

    1338 Words  | 6 Pages

    Ankita Batra Section 13156 The Effect of pH Level on Starch Digestion by the Activity of Amylase and the Examination of the Rate of Starch Disappearance Using Iodine Solution Introduction A key enzyme found in the saliva of humans, alpha-amylase, is involved in the early stages of starch digestion. This type of amylase is classified by its glycosidic bonds and is mainly found in the bodies of animals. The digestion of starch will begin with the enzyme in saliva and will continue to break down starch

  • The Effect Of Low Ph On Enzyme Activity

    1007 Words  | 5 Pages

    The Effect of low pH on Enzyme Activity Name Institution Affiliation Outline Enzyme: Amylase Source: Barley Substrates: Starch from potatoes Iodine Method: Time-based experiment on the enzyme 's reaction to converting Starch into sugars by testing the amount of time in which a 2 cm3 of starch solution would be converted to sugars. Control Group: • Amount of Iodine • Amount of Starch Sample Size: 1.50 g Introduction Enzymes are typically proteins and act as catalysts for various

  • Ph Buffer Using Cabbage Indicator

    7:50 Lab 1 February 2, 2015 pH and Buffer – Using Red Cabbage Indicator to Measure pH Introduction This experiment was performed to evaluate the following hypothesis: Red cabbage indicator can be used as a measure of pH. According to Campbell, et al, in Biology: Concepts and Connections, red cabbage contains a water-soluble pigment called anthocyanin that changes color when it is mixed with an acid or a base. The pigment turns red in acidic environments with a pH less than 7 and the pigment

  • effect of pH on amylase activity Essay

    Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case, amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example, may taste sweet to us, because they contain starch. The optimum pH for pancreatic amylase is the pH of 7. In the experiment

  • A Person 's Normal Ph Range

    971 Words  | 4 Pages

    A person’s normal pH range is between 7.35 and 7.45. (Tortora, G., Derrickson, B. H. ,2014-01-22). This range is important for the body to function properly. There certain conditions that can cause the pH range to fluctuate. Acidosis is a condition in which the blood pH is below 7.35 and alkalosis is a condition in which the blood pH is higher than 7.45. Significant changes in pH range can affect cellular function and possibly lead to death. “Your blood needs the right balance of acid and basic

  • The Effect Of Low Ph On Enzyme Activity

    Final Applied Lab Project: The effect of low pH on Enzyme Activity Thomas Long Biology 6380: Introduction to Biology (2155) Summer Semester   Final Applied Lab Project Introduction What are Enzymes? Enzymes are proteins that initiate change. The enzymes found in the human body are naturally occurring. They catalyze, or accelerate, all normal biochemical reactions in the body. Enzymes are responsible for all metabolic functions and many are vital for life itself. These proteins are highly specific

  • Determining The Ph Of Household Items

    the pH of Household Items March 22, 2016: Sara, Sam Introduction: Everyday household items can be seen as just “household items”. However, it is often not realized that we could actually determine the pH very easily. It could also be important to know the pH in everyday life. For example, it is important to keep track of human pH levels. Some people are curious to see the pH of their own body, which is a great use to keep acidic levels leveled. Another use in real life is determining the pH of pools

  • Lab Report : Ph Titration

    1390 Words  | 6 Pages

    pH Titration Practical Write Up: Introduction: This experiment includes a standard solution, which according to Lewis, R. and Evans, W. “is a solution of known concentrations”. They also stated that “the procedure in finding the concentration of a solution is called volumetric analysis. It involves reacting a solution of known concentration with one of the unknown concentration, in order to determine the equivalence point”. Titration is a technique where one reactant is slowly added to a second

  • 7.03 Lab Ph Essay

    775 Words  | 4 Pages

    ----------- --------------- = 0.03 mol HCl 1000 mL 1 L Conclusion: 1. Describe the graph of pH values over the course of the reaction in Part II. Was the change in pH consistent over the course of the reaction? Do your best to explain the reason for the shape of the pH curve in your own words: Yes, the change in the pH curve increases for each trial, and in consistent in its growth. I believe this was because of the increased amount of NaOH. 2. Why

  • The Effect Of Ph Levels On The Rate Of Activity Of ⍺-Amylase.

    2034 Words  | 9 Pages

    The Effect of pH levels on the Rate of Activity of ⍺-Amylase Ryan Andrew Introduction: Enzymes are some of the most important chemicals in the human body. Without them, humans and many other organisms would simply be unable to live. Our dependence on enzymes comes from their nature as biological catalysts, substances that speed up chemical reactions without being used up or changed (, 2017). They allow chemical reactions in our body to occur at a rate that is acceptable
