Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

How do you love when your heart’s filled with fear? How do you forgive when it’s so hard to forget? The story of African-American Antwone Quenton Fisher “Fish”(played by Derek Luke) leads people to ask these kinds of questions. An important person in his life being his psychiatrist Dr. Jerome Davenport (played by Denzel Washington) from the navy helped Antwone with his issues and anger by being there for him to talk to and release all of his stress and pain that he has held inside throughout his

Would You Have Quit? If I was a soldier in the American Continental Army during the Valley Forge time period‚ I would probably have quit the war. The reason that I would want to quit is i wouldn’t want to fight in a war‚ at all. I don’t think that fighting and killing is the answer to a country’s problems. However‚ if i was in the war then I would have quit because times were hard for the soldiers and for the people who were supporting the war‚ the Americans were losing the war‚ and they were

In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

Break Break Break by Alfred Lord Tennyson The poem ‘Break Break Break’ by Alfred lord Tennyson was written in 1834‚ the year after the death of one of his closest friends; Arthur Henry Hallam. Hallam and Tennyson had been very close for almost six years‚ and Hallam had been engaged to Tennyson’s sister‚ so his fatal brain hemorrhage in 1833 came as a great shock to Lord Tennyson. Hallam’s death affected him so much that nineteen years later he named his son Hallam.The literate subject of the poem

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate

Enzyme Catalysis Lab Problem: Before the lab‚ one should understand: • The general functions and activities of enzymes; • The relationship between the structure and function of enzymes • The concept of initial reaction rates of enzymes; • How the concept of free energy relates to enzyme activity; • That change in temperature‚ pH‚ enzyme concentration‚ and substrate concentration can affect the initial reaction rates of enzyme-catalyzed reactions; and • Catalyst‚ catalysis‚ and catalase

Megan Kubatzke 4th Hour March 1‚ 2012 ACT Paper How would you feel if you were being constantly monitored at school? Well‚ that’s what many high schools in the United States are currently doing; installing security cameras in various locations of the school. Security cameras in high schools are a good thing and all high schools should be investing in them. They make the school a safer environment‚ deter the wandering of students‚ and can help monitor behavioral changes

HOW TO BREAK A BAD HABIT Breaking a bad habit is and can be very hard to do. To start a habit is kind of simple once you think of something like smoking‚ then you have already started the bad habit by thinking of smoking. However when they think they have broken the habit‚ they will fall back to the same habits again when they face problems in life or have some stress in their life after breaking the habit. To keep from falling back in the bad habit‚ you will need some support from your family or
