Factors that Affect the Rate of Reaction of Peroxidase Purpose: To determine the effect of various factors on the rate of reaction between an enzyme and its substrate‚ and also to determine the optimal ranges under which the enzyme activity is maximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme will increase until it reaches optimum pH range (pH 7) because the

Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins‚ they act as catalysis (speed up chemical reactions). If enzymes didn’t exist‚ biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists

solution would be put into the cuvette at precisely 30 seconds and so time would not have an effect on my results. I also used separate pipettes to measure out the starch‚ amylase and distilled water so that the solutions don’t mix together before the reaction should start. Also‚ I repeated each of my experiments two times to make sure I get accurate

of ATP‚ Adenosine Triose Phosphate. This occurs by converting glucose into pyruvate via glycolysis. Pyruvate is then transported into the mitochondrial matrix via active transport. Numerous reactions‚ catalyzed by a multi enzyme complex then occur‚ where the pyruvate is decarboxylated as shown in the reaction below. Pyruvate + NAD* + CoA ? acetyl CoA + reduced NAD + Carbon Dioxide This experiment shall be carried out via the manometric technique‚ where there are two different environments with

Measurement of Capacitance using Arduino – An Interrupt-based Approach: Part I SAIKAT PATRA‚ SHIBENDU MAHATA Introduction Capacitive sensors are widely employed to measure various physical and chemical process parameters such as displacement‚ acceleration‚ thickness‚ force‚ pressure‚ stress‚ level‚ and humidity. The measured value of capacitance is then calibrated in terms of the process parameter for indication and/or control applications. This project presents an interrupt-based approach by

affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles

Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. Enzymes are catalyst for biochemical reactions; Enzymes lower the activation ATP so a reaction can begin over the energy barriers. In this lab‚ a discussion of the enzymes reaction to heat will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches too

the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1.09 minutes. Then last of all‚ we tested the boiling water (63 degrees) which had a large improvement from the last two with a rate of reaction of 43.5 seconds. This showing development in the rate of reaction

Enzyme Reaction Rates Under Different Conditions Introduction In this lab you will observe how the rate of a reaction is changed as certain factors are changed. You will observe how changing factors like temperature‚ pH‚ substrate concentration‚ and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the
