When comparing the three different Substrate Concentrations (3%‚ 1% and 0.3%) as which one was the fastest to react‚ I hypothesized that the reaction would occur the fastest with the 3% hydrogen peroxide (the highest amount of concentration) because the higher the concentration the more faster the reaction occurs and helps produce or break up the enzyme. After testing all three of my substrate concentrations with 10 trials each‚ my data showed (first graph) that the 3% substrate concentration had

Factors which Affect the Activity of the Enzyme Catalase Purpose: Must include: background information about concepts involved in the lab‚ statement of purpose of the lab identification of independent and dependent variables. A hypothesis is often not necessary or appropriate. Enzymes are proteins that speed up chemical reactions in cells. They break down molecules called substrates. Each enzyme has only one substrate that it breaks down. Enzymes are produced in the cells of the body

This is an outline of the three-step writing process‚ which should apply to your analysis of a case study. Answer the case questions related to each step directly on this form. For the three-step process questions‚ you may use short phrases and sentences for your answers. Then add a page break‚ and write your response as directed in the case study and save the document as one file. Student name I. Plan A. Analyze the Situation 1. What is your general purpose?

Enzymes are organic catalysts‚ usually proteins that speed up metabolic reactions. They lower the amount of energy needed for reactions to progress in cells. In enzymatic activity‚ the molecules at the beginning are called substrates. Lactose metabolism is when lactose is destroyed‚ maintained or produced. For instance‚ being lactose intolerance that’s where lactose is destroyed. Metal cofactors in enzyme activity are required to function properly. The Effect of Temperature on Enzymatic Activity:

Enzymes and Their Importance in Plants and Animals Enzymes are large proteins that are responsible for catalysing thousands of metabolic processes that sustain life. Enzymes work similarly to those catalysts used in industry by lowering activation energy and therefore dramatically speeding up the rate of a reaction‚ however‚ these biological catalysts are highly selective to their substrate. Almost every chemical reaction that occurs in a cell requires enzymes in order to occur at rates required

to see the effects of enzyme concentration on the reaction rate. Part 2: Effect of Substrate Concentration Purpose: The purpose of this part of the lab was to find the effect of substrate concentration on enzyme activity. Part 3: Effect of Temprature Purpose: The purpose of this part of the lab was to determine the effect of temperature on the rate of enzyme activity. Part

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein

the enzyme did not work as efficiently‚ even with the extra energy‚ as they had become deformed. Where the enzyme does not work so well or does not even work at all the active site if the enzyme had changed. The enzyme had not died as it is not a living organism. With the shape of the active site changed the enzyme is unable to perform the "lock and key" action the enzyme is meant to do in order to catalyse a reaction. The specified enzyme is shaped to "lock" on to the substrate. Where

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? Proteins
