Patrick McCrystal Enzymes: Natural Catalysts Enzymes are catalytic proteins‚ meaning they speed up chemical reactions without beingused up or altered permanently in the process. Although various enzymes use different methods‚all accomplish catalysis by lowering the activation energy for the reaction‚ thus allowing it tooccur more easily. Enzymes have very specific shapes (conformations). Part of the conformationis the active site of the enzyme‚ where the actual catalysis occurs. The specific molecule

ABSTRACT EXAMPLES Writing an Abstract – Examples Each student who completes a science fair project must write an abstract to be displayed with the project. An abstract gives the essence of the project in a brief but complete form — it should not exceed 250 words. Judges and the public should have a fairly accurate idea of the project after reading the abstract. The abstract must focus on the current year’s research and give only minimal reference to previous work. Details and discussions should

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

ABSTRACT Typing has been frequent these days‚ especially because of our fast changing technology. It is done by everyone‚ from professionals to students and to anybody who has a computer or similar device. In fact‚ typing has been essential to work and to assignments‚ and typing speed had become a major role-player. Mozart Music has already been proven to improve vision‚ and motor coordination of a person. It is highly controversial and became a topic of debate between some psychologists. The

The Rate of Reaction that Enzyme Concentration‚ pH‚ and Temperatures Have on the Amylase Enzymes Color Disappearance Abstract: Compare reaction rates of the concentrations‚ pH’s‚ and temperatures of the enzyme Amylase. At what concentrates do the substrate molecules collide with each other‚ making the reaction possible? At what pH levels do the 3D molecular structures change breaking the H-bond and/or denaturize? At what temperatures do the collisions of the substrate molecules happen

Thesis abstracts / 75 Writing a structured abstract for the thesis James Hartley suggests how to improve thesis abstracts (From Psychology Teaching Review‚ 2010‚ 16‚ 1‚ 98-100) Two books on writing abstracts have recently come to my attention. One‚ Creating Effective Conference Abstracts and Posters in Biomedicine: 500 tips for Success (Fraser‚ Fuller and Hutber‚ 2009) is a compendium of clear advice – a must book to have in your hand as you prepare a conference abstract or a poster

Part 2: Effects of Environment on Mitosis. Experimental Hypothesis: If we put onion root tips in IAA solution then the rate of Mitosis will increase. Null Hypothesis: There will be no difference Part 1- Post Lab Question If a cell contains a set of duplicated chromosomes‚ does it contain any more genetic information than the cell before the chromosomes were duplicated? No‚ because if it is duplicated‚ it would have the same number of chromosomes unless there was a

Chapter 9 Study Guide 1. Explain the difference between aerobic respiration and fermentation. Fermentation is partial degradation of sugars that occurs without oxygen. Aerobic respiration consumes organic molecules and oxygen and yields ATP. 2. Diagram for photosynthesis and respiration 3. What are redox reactions? What is the difference between reduction and oxidation reactions? Redox reactions are chemical reactions that transfer between reactants. In oxidation‚ a substance loses

Exercise 4 Lab Report (3) Individual: Prepared blood slide (a.) Compare red and white blood cells - what cellular features are present in white cells but not in red blood cells and vice versa? Include a digital image of the blood cells present in the permanent dry. Red Blood cells carry hemoglobin inside of them which helps carry oxygen from the lungs to the rest of the body. Hemoglobin is what gives blood cells the red pigmentation. The amount of blood cells present in the blood give it
