A Discussion on the Impact of Concentration of Substrate Hydrogen Peroxide on Enzyme Catalase
INTRODUCTION The enzyme catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown here, 2H2O2-------------------*2H2O O2. It is one of the fastest known enzymes and its turnover number is 6 million, which means the number of substrate molecules which one molecule of the enzyme turns to prod...

An Introduction to Telomere and Telomerase
An Introduction To Telomere and Telomerase The telomere-telomerase hypothesis of aging and cancer is based on the findings that most human tumors have telomerase activity while normal human somatic cells do not. An emerging hypothesis is that the up regulation or reexpression of telomerase is a critical event re...

An Experiment to Determine the Effects of an Enzyme's Concentration on the Breakdown of Starch
For this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down...

How Enzymes Work in the Human Body
Hypothesis – Hydrogen peroxide will breakdown to oxygen and water in the presence of Catalase. The reaction will increase with increasing enzyme concentration when molecules of hydrogen peroxide are freely available. However, when molecules of the substrate are in short supply, the increase in rate of reaction is limited an...

The Effects of Temperature on Enzyme Catalase
Aim: To investigate the effect of temperature on the enzyme catalase. Prediction: Using my existing scientific knowledge, I predict that as I raise the temperature to 30, 35, and 40, this is where we will see the greatest reaction. I predict this because enzymes are designed to react best at the body temperatures of the a...
