  • An Experimental Setup Will Be Tested With A Ph Meter Placed Inside Each Water Bottle

    1134 Words  | 5 Pages

    Introduction The experimental setup will be a pH meter placed inside each water bottle of water to check the acidity in each one, and it will be tested with a pH meter. The purpose of the investigation is to see which company of water bottles has the highest pH level. The independent variables are the different companies of water, the dependent variable will be the pH level of the water, and the controlled variable will be the pH meter, the computer and wires, the glass of water, and the distilled

    of enzymes depends on a number of factors, such as temperature, pH and the concentration of the enzyme just to name a few. This experiment was conducted to show the effects of different pH levels on the activity of the catalase enzyme, the data obtained in this experiment supports the initial hypothesis of the experiment which states that the catalase enzyme will function optimally at a pH of 7 and efficiency will decrease as the pH of solutions moves further away from 7. This is true because in

  • With Reference to Acid-Base Balance Explore the Role of the Respiratory System in Maintaining Blood Ph?

    2975 Words  | 12 Pages

    Interprofessional Studies. With reference to acid-base balance explore the role of the respiratory system in maintaining blood pH? ‘We live and die at the cellular level’ (Reid, 2011). Homeostasis is crucial for normal cellular function. Acid-base homeostasis is the part of human homeostasis and refers to the balance between the production and elimination of H+ hydrogen ions (pH) within the body fluids (William, Simpkins, 2001, p.236). Metabolic reactions within the cells often produce a huge excess

  • A Study to Evaluate the Changes in Salivary ph, after Consumption of Different Snacks and Beverages

    620 Words  | 3 Pages

    Materials & Method The present study was a clinical study carried out to evaluate the changes in salivary ph, after consumption of different snacks and beverages and to estimate their oral clearance time. SAMPLING: 60 randomly selected undergraduate students from hostel inmates of K.D. Dental College and Hospital, Mathura were examined. Out of these, 5 subjects were selected on the basis of following inclusion and exclusion criterion: Inclusion Criterion: • Subjects who were caries free i.e. DMFT

  • Observing How The Enzyme Catalase Of Chicken And Beef Livers Breaks Down Hydrogen Peroxide At Varying Ph Levels

    1443 Words  | 6 Pages

    at varying pH levels and temperatures. Purpose: The chemical hydrogen peroxide(H₂O₂) is broken down by the enzyme catalase. Hydrogen peroxide is a byproduct formed in cellular reactions that, if not broken down, could inflict severe damage to the cell. Catalase is an enzyme that breaks down hydrogen peroxide in to water and oxygen. How efficient and strong the enzymes reaction to break down H₂O₂ determines largely on temperature and pH level. An enzyme only functions within a set pH and temperature

  • Enzyme Kinetics Lab Report: The reaction rate of enzyme, '-amylase in Starch-Iodine solution at different temperatures and pH levels

    the relationship between enzymatic reaction affected by temperature and pH. Through the testing the enzyme at different temperatures, and different pH levels; it would determine at which temperature and pH level the enzyme worked the most efficiently. Analyzing absorbance of the solutions with spectrophotometery will determine the reaction rate. To test the optimal pH, the starch and a buffer were combined at a specific pH level and tested the absorbance of a solution at various times. To resolve

  • How Does Red Cabbage Extract As An Indicator Used To Determine Ph

    469 Words  | 2 Pages

    Determining pH Introduction: In this Lab report we will be using Red Cabbage extract as an indicator to determine the pH of substances. The purpose of this experiment is to see if and how base and acids react. Indicators are chemicals that change color depending on the pH solution that they are dissolved in. This experiment will determine which items we use to determine ph. The pH of a solution indicates its acidity or alkalinity. There is a ph. scale that determines if the items

    The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang, osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang, 1997). Osmosis is able to maintain osmotic pressure and regulate a cell's volume. In a hypotonic () or hypertonic () environment

  • Ph and Buffer Solution

    1998 Words  | 8 Pages

    Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides, this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution. Methods Verification of the Henderson-Hasselbalch equation

    Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds, pH = 7.4 2. At 40 seconds, pH = 7.4 3. At 60 seconds, pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so, how? No, the pH level of the blood did not change during normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes, the pH level was always within the normal range for human body. 6. Did the PCO2 level change during the course of normal
