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

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get

Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

Influence of Concentration on the Activity of Amylase Abstract Does more or less concentration speed up the reaction rate of amylase in starch? In this experiment diluted solutions of amylase were created and then tested using a starch solution‚ I2KI for reaction times. The answer to the question was proved to be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva of most animals and in humans. Amylase hydrolyzes starch

The Effect of Substrate Concentration on Initial Reaction Rate The purpose of this study is to identify the relationship between substrate concentration and initial reaction rate provided that substrate concentration is much greater than enzyme concentration. Enzymes are essential to life as they are required for many vital metabolic reactions to occur. To adequately explain the properties of enzymes‚ it is assumed that an enzyme-controlled reaction takes place through an enzyme-substrate
Premium Reaction rate Enzyme Chemical reaction
Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present

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

the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed to be 24%.
