Effect of changes in substrate concentration on the reaction rate of an enzyme IB biology Internal Assessment 3/23/12 Research Question: Effect of changes in substrate concentration amount on the reaction rate of an enzyme Introduction: In this experiment‚ the substrate is hydrogen peroxide. The purpose of this investigation is to find out the relationship between the substrate concentration and the rate of reaction. Substrates are molecules that are acted upon by enzymes. For instance‚ amylase

May 1‚ 2013 Enzymes as Drug Targets Enzymes are defined as any of numerous proteins produced in living cells that accelerate or catalyze the metabolic processes of an organism. Enzymes are usually very selective in the molecules that they act upon‚ called substrates‚ often reacting with only a single substrate. The substrate binds to the enzyme at a location called the active site just before the reaction catalyzed by the enzyme takes place. Enzymes can speed up chemical reactions by up to

ABSTRACT Enzymes are highly specific and can distinguish isomers of the same molecule. The enzyme invertase specifically catalyzes the reaction of the conversion of sucrose to its individual carbohydrates glucose and fructose. It does not catalyse the reaction of maltose to 2 glucose or lactose to galactose. In this experiment‚ titrimetric and spectrophotometric methods were used to determine the specificity of invertase by determining the amount of glucose converted from the given disaccharides

The Nine Steps of Accounting Cycle CheckPoint Step 1 in the accounting process is to analyze the transactions. This would include revenue‚ expenses‚ etc.‚ anything that the company received or paid during the time period. Step 2 is to journalize these transactions. To take the information and correctly post each transaction with a debit and credit line item. Step 3 is to post the journal information into an accounting ledger that shows all of the line items as totals in their respective

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

by finding a type of art they are comfortable with doing. Some artists do not like to make art that looks like anything someone has seen before. There are hundreds of different categories of art. Those categories can fall into one of three main types. The three main types in which a piece of art can fall under are representational‚ abstract‚ and nonrepresentational. Representational art is art in which the artist attempts to capture the image exactly as it appears. There are several different subcategories

interesting questions. Why do we find some jokes humorous and not others? What can we define as amusing? And what philosophical value does ‘humour’ have in our lives. This essay will be exploring the three main theories of humour and the important of humour in Nietzsche’s philosophy and life. The first of the main theories of humour is the Incongruity Theory. The Incongruity Theory is the idea that humour is derived from surprise. This is‚ the sudden revelation of a previously concealed fact. The first
