In biology‚ energy is needed for any process or reaction. Life would not exist without the presence of enzymes (Phillips‚ 2017). Through chemical reactions‚ this energy is created and is controlled by a catalyst‚ enzymes. Enzymes are known as proteins that are produced in living cells that speed up the metabolic processes of an organism. These catalysts speed up these reactions by decreasing the activation energy‚ how much energy is needed for a chemical reaction to happen (WBC‚ 2015). An enzyme-substrate

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

Lab: Inhibiting the Action of Catechol Oxidase By: Kimberly G. Introduction: In this lab‚ Mr. Greene ’s sixth period AP Biology class split into groups "to investigate inhibition of enzyme activity by specific chemicals called inhibitors" (1). Group three pondered this lab ’s inhibitor‚ phenylthiourea (PTU). Is it a competitive inhibitor? That is an inhibitor that literally "competes" with the substrate by mimicking it‚ and thus "wins" the position at the active site of the enzyme. The blocked

Enzyme assay lab report Health and safety: 4-nitrophenol is harmful. Introduction: Enzymes are quaternary structured proteins that are specific biological catalysts that speed up a reaction without being used up. They contain an active site that allows substrate to bind to a specific area on the enzyme which is of a complimentary shape of the substrate. There are two models of enzyme action‚ the Lock and Key model and the Induced Fit model. The Lock and Key model states that the enzyme has a specific

Enzymes and ATP Enzymes act as protein catalysts in biochemical processes Enzymes bind to a substrate and forms the enzyme substrate complex. Enzymes work by lowering the energy of activation. Activation energy must be supplied for the reaction to begin‚ once supplied‚ the reaction can proceed on its own. Enzymes can speed up events. They are not used by during the reaction because the enzyme stays the same‚ it does not change during the reaction. (Hudon-Miller‚ Enzymes‚ 2013) Enzymes act as

(Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars in the lower jaw (one side). The total number of incisors‚ canines‚ premolars‚ and molars (upper +lower jaw) multiplied by 2 would equal

Solutions of different concentration were made from the stock solution and placed in test tubes. 2. All test tubes were labeled appropriately‚ according to table below‚ and Benedict’s test was carried out on the various dilutions for 5 minutes. 3. The colours of the solution were observed and heights of precipitate formed were recorded. The test

Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature.
