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

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

form the structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell and is named according to the substrate they specifically affect. An enzyme works best under optimal conditions pertaining to temperature‚ pH level and salt concentration1. In unfavorable conditions enzymes will become denatured

I. Preparation A. Choosing 1. You should choose the fruits that you like. a. For example‚ if you desire to gain more different fruits enzymes or make the glass bottle more colorful‚ you can choose four or even more kind of fruits. There is no limitation. But‚ you must include one fruit‚ lemon. It helps to kill the bacteria of the drink. B. Composing 1. The ratio of components should be 3‚ 1. It means 3 parts of fruits‚ 1 part of sugar. You can follow this ratio to determine the amount of fruit

The Behavior of Proteins: Enzymes Enzymes are Effective Biological Catalyst Catalysis- speeds up metabolism to allow production of products. Enzymes- Highly specific and most efficient catalyst that speeds up metabolism or rate of reaction in organisms by factor up to 10^20 (globular proteins) Nonenzymatic catalyst- enhance by 10^2 -10^4 Ribozymes- acts for catalytic activity in RNA’s Kinetics versus Thermodynamics Standard free energy change- difference between the energies of the reactants

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from

Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or
