Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

Broadly speaking‚ enzymes are proteins that is produced to perform as a biological catalyst in chemical reactions. Catalyst are used to increase the rate of a chemical reaction. In this study‚ we performed two different experiments that investigated the effect of varying substrate concentration‚ and the effect of temperature on the rate of Enzyme-Catalase reaction. In experiment one (i.e. the effect of varying substrate concentration on the rate of enzyme-catalase reaction) we tested the hypothesis

Enzymes INTRODUCTION Enzymes are protein cells and they are found in the gut. They help to break down the food you eat. Enzymes are produced by living cells and they speed up reactions because they are biological catalysts. If we did not have enzymes‚ the reactions in our cells would be too slow to keep us alive. This means that they are extremely important for our survival. The properties of enzymes are: ⋆ They can be used many times‚ because they can speed up reactions without

floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg float

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

Lambda DNA with restriction enzymes. Aim: The objectives of this experiment are: Become more familiar with using micropipettes. Use restriction enzymes to cut DNA at specific sites. Use Ligase to rejoin some of the cut/separated DNA fragments. Learn to separate DNA using electrophoresis. Introduction: Restriction enzymes are proteins which cut dsDNA at specific regions depending on the enzyme used‚ determined by the nucleotide sequence of the DNA‚ i.e. each enzyme recognises specific nucleic
