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+

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

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

Gung Ho is an American comedy movie released in 1986. The story of the movie is about the takeover of an American car plant by a Japanese corporation named “Assan Motors”. In a small town named “Hadleyville” in Pennsylvania‚ the local auto plant is closed for nine moths which supplied most of the jobs in the town. The former foreman of the plant goes to Tokyo and does a presentation to convince the “Assan Motors” corporation to re-open the plant and provide jobs for the town. The company agrees and

catalase activity performed better at 0⁰C than at 100⁰C. Strangely‚ 50⁰C outperformed 37⁰C. Catalase activity was higher for intermediate temperatures such as 37⁰C and 50⁰C than the extreme temperatures such as 0⁰C and 100⁰C. Overall the rate of reaction peaked at 28⁰C and every other temperature had a lower maximum rate of reaction. DISCUSSION The results do not support the hypothesis that optimum temperature would be at 37⁰C. The results do not reflect the textbook narrative of enzyme activity. Enzymes
