    Effects of hyperventilation on CO2 and pH levels Alidrin Armandico Physiology Lab 142 Egle Ortega Aprill 25‚ 2014 Abstract The aim of this experiment was to analyze how pH and carbon dioxide (CO2) levels in the blood change during hyperventilation and how the renal system compensates for this condition. Hyperventilation decreases CO2‚ increases pH‚ and lowers H+ levels which then results to respiratory alkalosis. In the experiment‚ we used the PhysioEx 8.0 software to simulate hyperventilation

    College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

    The Effects of Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH.  BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which

    The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

    The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper‚ which covers all ph’s‚ but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+

    Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

    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
