Exploring Enzymes - Ground-Up Tissue Activity Abstract Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined

Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

Enzymes are important components of life‚ facilitating reactions that are necessary for an organism to live. Enzymes can be very specific to what environment they function best in1. Numerous environmental impacts were 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
Premium Enzyme Chemical reaction Catalysis
Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

experiment on the significant in strength of the enzyme by using three different test tubes and measuring the amount of product they give off. To determine this we are going to test the amount of color absorbance by using a special tool to help us understand our results. We will see how our end results show the effect of the amount of concentration we apply to each test tube. The results would be shown by the support of two graphs. Introduction: Enzymes are highly important because of the significant

Lab #5-Enzymes NAME DATE LAB PERIOD Introduction Enzymes are proteins‚ though highly complex and diverse‚ they serve one basic function; to work as an organic catalyst. A catalyst‚ as defined by Merriam-Webster dictionary‚ is a substance that enables a chemical reaction to proceed at a usually faster rate ("Catalyst-Definition and more."). They function by reducing the activation energy‚ or energy required to start a reaction. The way enzymatic reaction works cannot be altered‚ but the

Hypothesis: If pH is increased or decreased past the enzyme’s optimum pH‚ the number of products produced by the enzyme will decrease because the enzyme will become denatured. Variables: The Independent variable is the pH of the environment. The uncertainty of pH is ± 1. pH is a unitless value. The Dependent variable is the number of products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant

Restriction enzymes (or restriction endonucleases)‚ originally isolated from Haemophilus influenzae in 1970‚ are enzymes within a cell that cleave foreign DNA within a specific and predictable nucleotide sequence (known as a restriction site) regardless of the source of such DNA.

Omar Shbeeb Toothpick Enzyme Lab 9/25/13 Introduction Enzymes are used in all metabolic reactions to control the rate of reactions and decrease the amount of energy necessary for the reaction to take place. They are responsible for the thousands of chemical interconversions that sustain life. Enzymes are referred to highly selective catalysts‚ meaning they speed up the rate of metabolic reactions. To react‚ they need to find a perfect match with a substrate. They converge at a place called an
