Effects of Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical

Testing the pH of Common Household Substances Lab Background Information: The pH scale is used to determine the acidity or basicity level of liquid solutions. If a solution scores a pH level of 1-6 it is an acidic solution‚ 1 being the most acidic and 6 being the least acidic. If a solution rates a pH level of 7 it is a neutral solution‚ meaning it is neither an acidic nor a basic solution. Lastly‚ if a solution is 8-14 on the pH scale it is a basic solution‚ 8 being the least basic and 14 being

Examine how factors can cause changes in economic activity Economics activity is the production‚ distributions‚ exchange and consumptions of goods and services. Businesses and consumers can cause it to increased and decreased‚ when it increases it means that the value and amount of goods and services are increasing as well‚ many factors can change how the economic activity for example interest rates‚ consumer spending and many more. Interests rates is one of the main factors that cause changes to the

Determining the Optimal Temperature and PH of Barley Amylase Abstract The purpose of this experiment was to find the optimal temperature and pH of barley alpha-amylase. I hypothesize that the optimal temperature would be 55 degrees Celsius and the optimal pH would be 5.5. In this experiment‚ the starch is used as a substrate to examine the optimum temperature and pH for the reaction of alpha amylase. It is known that the measuring of disappearance (absorbance) of the substrate starch with iodine

brought you to each question‚ and your conclusions. The questions are as follows: 1. Metaphysics: What is real? Is the physical world more or less real than the spiritual or psychological world? Is there such a thing as a soul? If so‚ how does it survive outside of a physical body? Do all people have free will‚ or are their lives determined by fate? 2. Epistemology: How is anything known? What is the basis for knowledge? Is it innate reason‚ experience‚ or something else? Is all knowledge subjective

| Economic Activity Economics is concerned with humanity’s well being or welfare. It encompasses the social organization and the relationship involved in using scarce resources and available technology to satisfy seemingly unlimited human wants and in allocating those resources among diverse alternative wants. The key elements of economic activity are (1) human wants (2) resources‚ and (3) technology. Price theory (microeconomic

More testing‚ More Learning All students wish to finish their college year with a good grade. There is a lot to learn in every chapter of textbooks. Even if a student spends most of his time studying‚ he will get very stressed when a midterm or final comes. These exams will judge how well that student is doing for the whole entire semester. Patrick O’ Malley in “More Testing‚ More Learning” mentions that more testing provides students better learning opportunities because more testing forces students

September 10th‚ 2013 EXPERIMENT 1 LEARNING BASIC OPERATIONS: THE EFFECT OF PH ON A FOOD PRESERVATIVE Purpose: The purpose of this experiment was to investigate a competitor’s claim that the food preservative‚ sodium benzoate (C6H5COONa)‚ made by Fresh Foods International (FFI)‚ changed into a new substance in stomach acid. Stomach acid has a pH between 1 and 3 due to the hydrochloric acid content. Based on the net equation given in the book as well as the solubility of the product our hypothesis
