The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Question Give an account of how enzymes work with particular reference to factors that affect their activities. Answer All living things require catalysts to catalyse the reaction which they carry out to survive. Enzymes are the catalysts of biological systems without enzymes reactions in cells would occur all much to slow a rate and the organism would not survive. Most enzymes‚ with the exception of some RNA catalysts‚ are proteins. They often require a co factor such as zinc or iron‚ or a complete organic

The Effects of Human Activity on Climate Climate is a natural activity that can be defined as the weather conditions prevailing in an area in general over a long period of time (which can include temperature‚ air pressure‚ humidity‚ precipitation‚ sunshine‚ cloudiness‚ and winds) (“Climate”). The climate has been a part of our environment long before humans came to study it‚ and really took it into consideration. Now through the many negative environmental actions created by humans through beneficial

What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well be more

Enzymes Ashley Njeru Mrs. Booth Tuesday‚ March 19th 2013 SBI 4U INTRODUCTION: The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule‚ usually a protein‚ which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or

Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created

grouped into primary events that include the metabolism of residual lactose and of lactate and citrate. There are different types of cheeses because there are many enzymes that are used to make the cheese‚ and also there are endless forms of molds that help age cheese giving each cheese its distinctive taste‚ texture and appearance. Enzymes are used in many food production processes to speed up the chemical reactions‚ which reduces water usage and energy consumption. The original objective of cheese
