Jennifer Anatomy and Physiology Enzyme Lab Report Introduction The chemical reaction that is being studied is the hydrolysis of starch. The enzyme that is being studied is amylase. This experiment is looking at the effect of temperature on the rate of the enzymatic hydrolysis of starch. My hypothesis is that the higher the temperature the faster the hydrolysis of the starch would occur. The rationale behind this is that heat

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

Meerra Gandi‚ Erin Barody‚ Samantha Gutcho Title: The Effect of Adjusted Concentration of Hydrogen Peroxide on the change in reaction rate of liver catalase. Hypothesis: Null Hypothesis: If the concentration of the Hydrogen Peroxide is changed then there would be no change in the reaction rate. Alternate Hypothesis 1: I there is an increase in concentration in concentration of Hydrogen Peroxide then the reaction rate of the liver catalase will increase. Alternate Hypothesis 2: If there is an increase

HINTS ON WRITING YOUR REPORT Title: Enzyme activity Objective: To investigate the effect of temperature on amylase activity Design principle Background: Amylase activity products? (show the equation) Which factors will affect enzyme activity? How to study the rate of reaction? (e.g. rate of disappearance of substrates or rate of formation of products) Independent variable: temperature of reaction mixture or at which the enzymatic reaction occurs. It can be varied by setting water bath at

How Temperature Affects Amylase Activity Abstract This study of the effect of temperature on the enzyme amylase was performed to determine the relationship between the enzyme amylase and temperature. The rate of reaction was found to increase as the temperature of the environment was raised. As the temperature was raised from 5°C‚ 20°C‚ 35°C and finally to 80°C the rate of reaction followed this trend and also increased. However as predicted in the hypothesis of this experiment when the temperature
Premium Enzyme Chemical reaction Temperature
Enzymes- reduce the amount of energy required for the reactions they catalyse [accelerate]. -thus‚ increasing the rate of reactions that occur in living organisms. WITHOUT enzymes : metabolism would be so slow at body temp. that insufficient energy would be available to sustain life. -Many enzymes are “Intracellular”- used within the cell that produced them e.g. enzymes in respiration & photosynthesis -Others are “extracellular”-they act outside the

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate
