Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

Activity 3: “Using Sources” Emma Ballew Washington State University Tri-Cities For my lesson‚ I did “Using Sources”. 1) The first thing I learned was the 2 different ways to use sources to argue. The first way to use a source is by agreeing with the source (Atias‚ Lennard‚ & Zuckerman‚ 2013). This can be done in two ways. One way is to use the research that other sources have done (Atias‚ Lennard‚ & Zuckerman‚ 2013). Using the research of others can help to lay a foundation for a paper’s argument

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

standardized tests? We designed an experiment which would put an answer to this question. The experiment tests the spectrum of standardized test scores of those who ate breakfast versus the scores of those who ate nothing. This experiment would be a single blind study because the scientists would not be biased therefore they would have no reason to alter the test results; it is a purely research type experiment. There would be two groups involved in the experiment- the experimental group‚ which would

An Experiment To Show The Effect Of Exercise On The Body Aim The aim of the experiment is to find out the effect exercise has on the body‚ and why these changes take place in the body. Introduction Respiration is the physical process by which living organisms take in oxygen from the surrounding medium and emit carbon dioxide. The term respiration is also used to refer to the liberation of energy‚ within the cell‚ from fuel molecules such as carbohydrates and fats. Carbon dioxide and water

What was the effect of photography on painting in the nineteenth century? The photograph was developed in 1839 simultaneously in England and France by Talbot and Daguerre. That is the technique of chemically fixing of an image produced by exposure to rays of sun. William Fox Talbot was an English scholar and scientist who developed the negative and positive process. He used sensitive paper soaked in sodium hyposulphite called calotype. This became the basis for all subsequent photography. Photography

Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil.The amount of blue complex that starch gives with iodine can be measured by using a spectrophotometer. α-amylases are found in saliva‚ pancreatic juice‚ human breast milk‚ serum and certain tissues such as the liver. This enzyme catalyzes the hydrolysis of α (1-4) linkages in starch by breaking it down to maltose and some glucose. As the starch is broken down‚ the coiled structure of α-amylase is unfolded

The Stanford Prison Experiment was a very unique and brutal experiment. In 1973 the professor Philip G. Zimbardo set out to study how normal subjects such as college aged men would react as “prisoners” and “guards” in a mock prison setting. Stanford set up what they called a “mock prison” in the basement of Stanford University’s psychology building. During the experiment there were ten prisoners and eleven guards. The prisoners were stripped of their uniqueness by being dressed in matching smocks

Purpose To test whether the lunar effect is a reality or simply a myth‚ I will conduct a study to see if there is any correlation between the lunar phases and birth rate. Independent variable: Lunar phases Dependent variable: Birth rate Background The lunar effect is the idea that there is a correlation between the lunar phases and changes in living beings on Earth‚ including humans. Many people believe that the lunar effect on birth rate causes more
