lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions; “reactant molecules

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

Enzyme Catalysis Abstract: Catalysis is an enzyme that decomposes hydrogen peroxide into oxygen and water. In this lab we will conduct a series of experiments to determine the affects of; pH‚ temperature‚ and concentration change on such catalysis. After completing the experiments we determined that catalase works most efficiently when in a 27°c‚ 50% (5 ml of catalase – 5ml of water)‚ and a normal body pH of 7°.

AS Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides-

The main catalyst for conflict is fear My father loves to tell me stories about my great grand father‚ who was once a member of the Chinese communist army. I was told that although my great grand father fought many battles against the Japanese‚ he never fought because of his own believe or own hatred‚ the only reason for all his battles is because he was scared. The fear that China will be dominated by another empire and our family might suffer due to the lost of war has caused him to join the war

introduction to enzymes Enzymes are the foundation of energy and the life force in all living things. They are responsible for building‚ detoxifying‚ and healing the body. They are also the force that allows your body to digest and absorb food. Enzymes also regulate tens of thousands of other biochemical functions that take place in the body every day. Without enzymes‚ seeds would not sprout‚ fruit would not ripen‚ leaves would not change color‚ and life would not exist. Therefore‚ the study of enzymes has

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

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
