The rate at which substrate is converted into product during an enzyme-controlled reaction

Extracts from this document...

Introduction

GCSE Biology Coursework Aim I am going to carry out an investigation into the rate at which substrate is converted into product during an enzyme-controlled reaction. Introduction Thousands of chemical reactions happen in our cells. ...read more.

Middle

The reaction takes place on a part of the surface of the enzymes called the active site: This explains the enzyme action, which is also known as the lock and key mechanism. There are a number of factors, which can affect the rate of an enzyme-controlled reaction: ==> PH ==> Amount/concentration of substrate present ==> ...read more.

Conclusion

CATALASE catalyses the breakdown of hydrogen peroxide into water and oxygen: Catalase Hydrogen peroxide water + oxygen Catalase H2O2 H2O2 + O2 It is an easy reaction to follow as the oxygen that is released can be measured and then the rate of the reaction can be calculated. I will be using potato tissue as a source of catalase. ...read more.

    & substrate(2ml) each time, although changing the concentration of the substrate.(2.5%,5%,10%,15%,20%) I will also keep the amount of water in the measuring cylinder the same, and the concentration of the enzyme.

  2. To Investigate an Enzyme-Controlled Reaction.

    This will only occur when excess molecules of hydrogen peroxide are available. If molecules of hydrogen peroxide are limited the rate of products formed will be low.
