The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

First is how mass incarceration affects the communities. One of the first issues that is talked about in the article is this issue of Invisible Inequality. “Inequality worsens both crimes of poverty motivated by need for goods for use and crime of wealth motivated by greed”‚ (Barak‚ et. al.‚ 2015). This issue has many aspects but the main aspect of this issue is that when data is being collected for different types of community well-being studies such as unemployment the people that are incarcerated

Cultural diversity and Cultural shock Variety of behavior found among the people within or far apart from the nation can be termed as cultural diversity. The way they live till the way they think varies‚ within the one from next culture. It can be seen within the community‚ where the people from around the world lives and the way of thinking varies from us. It is one of the great aspects of life too in which we can learn about other cultures and learn the way they see. It not only helps to learn

Does globalisation pose a threat to cultural diversity? Globalisation poses a threat to cultural diversity because it is the cause of widespread cultural homogenisation. I will focus on Helena Norberg-Hodge’s 1991 book‚ in which she describes the recent cultural changes within a particular Indian community. In examining this text‚ I hope to show that globalisation truly does pose a threat to cultural diversity. In this essay‚ globalisation will be used as an umbrella term to describe the increased

reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

Analysis • Error Bars Analysis Evaluation • Improvement Assessment • Improved Experiment. • Reliability References Introduction: For this data analysis project‚ I conducted and experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that

Week 7‚ Question 1: What are some of the unique problems general classroom teachers might encounter when working with parents of culturally diverse backgrounds? (Culturally diverse does NOT mean only ethnically diverse but culturally diverse in any way as in the culture of poverty.) When it comes to working with parents the general classroom teacher has to deal with a lot of different parents and when the parents are culturally diverse it can bring up a variety of situations. First‚ a teacher might

Every single person has a unique way of expressing their cultural identity because no one grew up exactly the same. I wouldn’t have my identity if I haven’t carried morals and beliefs I had while growing up. I also gained characteristics that represent me from the society we live in today. My cultural identity can be best expressed by the word persistence. I have a lot of aspects in my life that shapes who I am. This includes my love for alternative music‚ writing & drawing to represent my opinions
