Catalysis

** The Low vs. High column shows how each protein band was influenced by the salt. If band was present in both conditions, it was noted what condition had and increase or if they were equal. Discussion I studied the expression of V. parahaemolyticus’ expression of OM protein when grown in a high and low salt condition. I hypothesized that V. parahaemolyticus would increase the expression of OM proteins in a high salt condition and lower the expression of OM proteins in a low salt condition. As shown

It was also due to the increase in the polarizability of the organic cage which strengthens the framework through van der Waals and charge-quadrupole interaction with the gas molecule [75]. Yang and coworkers [76] also synthesized the Li-doped HKUST-1/MWCNT composite through a post-synthesis route by doping the Li cations into the parent HKUST-1 MOF/CNTs. The gas uptake per effective specific surface area of doped material increased ca. 305% for CO2 compared to the unmodified HKUST-1 at 298 K and

In this particular lab, my team and I were determining and demonstrating how the change in pH level and temperature affects enzyme activity. Enzymes are proteins in living things that speeds up chemical reactions. We used a specific enzyme, catalase which breaks down hydrogen peroxide into water and oxygen. The oxygen released from the chemical reactions creates gas bubbles, also known as foam. By measuring the foam, we are able to determine how active the enzyme is. If there is a big amount of foam

How does the concentration of the enzyme in different tissue types affect the efficiency of Catalase in its efforts to reach a dynamic equilibrium within the cell? Enzymes undergo processes in order to maintain dynamic equilibrium at all organisational levels. Enzymes are biological catalysts that help complex reactions occur (Chem4Kids, 2015). A catalyst is a substance that increases the rate of a chemical reaction. This is justified because enzymes accelerate the rate in which a reaction

Biology 121 KS Lab Report IV 03/06/2018 Jannet Marin Testing the Effects of Temperature and pH on Potato Catalase Activity Introduction: To bear life in the cell, nearly all metabolic processes need enzymes. Enzymes are “macromolecular biological catalysts that help to speed up, or catalyze, chemical reactions.” The activity of enzymes is also affected by changes in the pH and temperatures. However, tremendously high or low pH and temperature values could cause complete loss of activity

Introduction An enzyme is a substance by a living organism that acts like as a catalyst to bring out biochemical reaction. So basically enzymes are molecules that speed up chemical reaction in all living cells.They are one of many main component of life today. In this lab we studied how the enzymes would react with the different types substances. Our discussion question, “Are enzymes specific”.The purpose of this lab is to gain knowledge of what will happen when enzymes are mixed in with different

THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY DB-16-0081 Co-partner: TIMORE NURDINOV Introduction The aim from this experiment is to observe the effect of factors such as pH, temperature and inhibitor on enzyme activity and how it works. Enzymes are proteins that act as catalysts within living cells. Catalysts increase the rate at which chemical reactions occur without being consumed or permanently altered themselves. A chemical reaction is a process that converts one or more substances

An Experimental Study on the effect of pH on Catalase Activity Maria Stavroula Zervoulakou Biology Standard Level (Block A) Mohammad Reza Mansournia Tuesday, February 27, 2018 An Experimental Study on the effect of pH on Catalase Activity Research Question: What is the effect of different pH on Catalase Activity? Background Knowledge: A globular protein that has the ability of speeding up chemical reactions, without itself undergoing any permanent chemical change, is called an

The Effect of Catalase Concentration, Hydrogen Peroxide Concentration, and Salt Concentration on Catalase T. Meinhardt R. Panther P. Frazier Introduction of Background Knowledge: Enzymes are a type of protein that catalyze chemical reactions and can speed up digestion of particles to be broken down, or speed up synthesis of particles to build molecules up. First a target particle (substrate) is attracted to an enzyme based in its shape and polarity. Next the enzyme isomerizes or changes shape due

Introduction To maintain basic life functions, cells have to perform reactions. Early chemists found that whenever certain chemicals were present in reactions, substances were changed from one form to another. These certain chemicals present in these reactions were named catalysts. These early chemists also found that enzymes were not consumed or altered in the reactions. Enzymes also lower the activation energy in cells causing the reactions to occur at a faster past. In our cells, enzymes are
