Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

Enzymes speed up chemical reactions and at the active site‚ a substrate can be broken down or two substrates can form a larger molecule. Hydrogen peroxide is broken down by peroxidase into water and oxygen which is released in the form of gas bubbles. If there is a large amount of bubbles‚ it means there is a large quantity of peroxidase breaking down the hydrogen peroxide. Denatured enzymes are enzymes whose shape has been altered and are no longer active (Wiggins). Ethanol is able to denature enzymes

project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the speed at which

17th‚ October 2010 Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the

think that more oxygen will be released from the Hydrogen Peroxide and Catalyse. We will be measuring the two main factors: - * Oxygen - the amount released from the Hydrogen peroxide * Time - The duration of the reaction The room temperature may be a factor that will affect our results.

results that higher concentration of iron cofactors shows the higher absorbance. The importance of the existence of iron in this reaction is that the peroxidases in plant cells respond to environmental stress by‚ in this case‚ catalyzing the conversion of toxic metabolic wastes‚ H2O2‚ into the harmless products‚ H2O and O2‚ faster. Therefore‚ as peroxidases help minimize and eliminate harmful chemicals‚ the iron cofactors that help peroxidase’s activity raise the possibility of plants’ survival in harsh

Biology Lab Report - Movement in and out of cells (4A) Shiang Chen Ting (24) Sec 313 Introduction The aim of this experiment is to explore the factors which affect the movement of materials in and out of the cells. The dark red or purple colour of Beetroots is caused by a pigment called betalain that is found within the vacuole of the beetroot cells. The pigment remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect

on Peroxidase Enzyme Claire Bell Biology 1130 Jazmen Myers Section 36 Abstract Peroxidase is a turnip enzyme; it is used in the oxidation of hydrogen peroxide to lower activation energy‚ speeding up the reaction. The activity of peroxidase is highly dependent on its environment and most importantly the pH level. Peroxidase has been the focus of many recent studies and is believed to possibly reduce swelling among other things. We conducted an experiment testing the effect different

tested for the enzyme peroxidase which catalyzes the decomposition of hydrogen peroxide. The basic decomposition reaction was carried out first without any environmental alterations. The hypothesis for this reaction was supported. The enzyme caused the amount of absorbance increase as time went on at a fairly constant rate (Figure 1). As shown in Figures 2A and 2B‚ pH has a large effect on the rate to which an enzyme catalyzes a reaction. The optimum pH for the peroxidase was 6. Each varying pH
