our experiment – enzymes catalyse reactions because they become an active site for reactions to take place. This lowers the energy that is needed for the reaction but at the same time‚ it increases the chance that they will happen. Enzymes have an optimum temperature range at which the reaction will work the best – in most cases the warmer the better. The reason behind this is because when particles become warmer‚

balanced interpretation of Ho Chi Minh to some a major extent‚ however there are some inconsistencies with views of historians. While the majority agree to some extent that Ho was either communist or nationalist some are divided by this theory and provide us with two different perspectives of Ho Chi Minh. Historians such as Osborne present us with a positive view of Ho and describe him as a great leader. However other historians have a negative view on Ho and describe him as an ineffective leader

enzyme-substrate complex. The catalytic action of the enzyme converts its substrate into the product or products of the reaction. Each reaction is extremely specific‚ distinguishing between closely related compounds‚ including isomers. For example‚ the enzyme sucrase will only act on sucrose and will not bind to any other disaccharide. The molecular recognition of enzymes is due to the fact that they are proteins‚ which are defined as being macromolecules with unique three-dimensional conformations. Therefore

pH and Living Systems I. Purpose: To observe the effects of pH change on an organic molecule. II. Materials: pH paper Droppers Ammonia Beakers (50ml) Paper towels water Glass stirring rods lemon juice forceps III. Procedure: Part 1: Initial pH testing 1) First use the wide range pH paper to test the pH of the liquids given. 2) When you test with the wide range paper first (which reads pH from 0-13) be sure

Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the

Chapter 1: Welfare State Describe the welfare state and its history in Holland Background information Up and till the end of the 19th century‚ people living on the countryside in The Netherlands‚ were used to living together and taking care of each other when needed. Whole families lived near each other‚ and supervised their children‚ took care of the sick‚ helped with birth and death‚ trained each other for work‚ and countless of other things. They were solidary to one another. But when in the

Lab on pH Levels Purpose: Throughout this experiment we are trying to learn how to take proper pH measurements using a pH meter. We also want to see the pH of different common liquids and record the change in pH when we add acids and alkaline liquids. The last reason we are conducting this experiment is to explain and show how fresh milk spoils by the change in pH. Materials: In this experiment we used graduated cylinders and glass beakers and added variety of ingredients including 50 mL of; soda

The reason why I think this could be a limitation is because each solution has an extreme acidic pH level like 1 or 2. As a result‚ I speculate the supreme acidity of the solution could negatively affect the pH measurer that could make it lose the originality to measure the right pH level for later product. Hence‚ it is crucial to have the pH measurer calibrated in a buffer solution so that the measurement can have a high accuracy overall. Thirdly‚ when measuring the

Distinction of pH levels of Orange Juice and Milk of Magnesia in comparison to Distilled Water Cooper‚ A.‚ Do‚ J.‚ Francois‚ F.‚ Olaleye‚ O. Lab Section LA: 06/20/2012 Introduction pH is the measurement of the concentration of hydrogen ions in a certain solution. Solutions or substances that have a higher concentration of hydrogen ions are considered acidic on the pH scale. Therefore‚ a solution with low concentration of hydrogen ions is basic on the pH scale. The pH scale is a universal means

The major is problem is that hospital’s senior management lacks the ability to identify and partner good leaders with ideal departments. Mary Ann’s leadership style is not an optimum fit for the Emergency Department. By definition‚ leadership style is “the leader’s behavioral pattern when acting to influence others” (Furtado‚ Batista‚ & Silva‚ 2011‚ p. 51). Mary Ann’s main concern is the hospital’s bottom line. She is more concerned with saving the hospital money than caring for her nursing staff
