scale? Hypothesis: Altering the pH of solution that pieces of apple are placed into has an effect on the degree of colour change that occurs when they come into contact with atmospheric oxygen. As the pH of solution increases‚ so does the degree of browning of the apple slice. Low pH solutions will cause the enzyme to be inactivated and therefore cause the degree of browning to decrease. As the pH increases so does the degree of browning‚ because the pH becomes closer to the enzymes optimum pH

Chapter 8: Hypothesis Testing: 8.1 Review and Preview: The two main activities of inferential statistics are using sample data to (1) estimate a population parameter (such as estimating a population parameter with a confidence interval)‚ and (2) test a hypothesis or claim about a population parameter. Hypothesis: a claim or statement about a property of a population Hypothesis test/test of significance: a procedure for testing a claim about a property of a population Population proportion

of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature and also the effect of inhibitors on enzyme activity

A hypothesis is a tentative statement predicting a particular relationship between two or more variables. If you want to know whether or not your study requires a hypothesis‚ ask yourself these questions: Are you undertaking a quantitative study? Does your study take an experimental approach to answer questions? Are you making a prediction about the phenomenon being studied? If your answer to these questions is ’yes’‚ then you will need a hypothesis‚ but if it is ’no’ then you will need a

INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical
