Affect of Concentration of Enzymes on Rate of Break Down of Egg White
Enzyme concentrations Hypothesis The higher the concentration of protease enzyme the higher the rate of breakdown of the egg white. This is because egg white is mainly formed of collagen, which is a protein, which is what the enzyme protease breaks down. The more enzyme there is the more enzyme substrate complexes are formed which break down peptide links between the monomers of the protein accelerating the amount of protein broken down in a space

Enzymes Essay
Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food, for stimulating the brain, for providing cellular energy, and for repairing all tissues, organs, and cells. There are three types of enzymes: metabolic enzymes, digestive enzymes, and food enzymes. Metabolic enzymes catalyse, or spark, the reactions within the cells. The body's organs, tissues and cells are run by metabolic enzymes. Without them our

Concentrations of Bile Salts on Lipase Enzyme
AIM The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat. BILE Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water, bile salts, bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine

Factors Effecting Enzymes
Factors Affecting Enzyme Action The activity of enzymes is strongly affected by changes in pH and temperature. Each enzyme works best at a certain pH left graph and temperature right graph, its activity decreasing at values above and below that point. This is not surprising considering the importance of * tertiary structure i.e. shape in enzyme function and * non covalent forces, e.g., ionic interactions and hydrogen bonds, in determining that shape. Examples: * the

Enzyme Regulation
Enzyme Regulation Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst. Enzymes are proteins, the functioning of the enzyme

Enzymes
Enzymes are biological catalysts that speed up the rate of a chemical reaction. Being a catalyst, enzymes are not consumed during the reaction and are able to be used numerous times. Enzymes work by lowering the activation energy for a reaction, dramatically accelerating the rate of the reaction. Enzymes are composed of proteins, their exact function is determined by their structure, which is a combination of the sequence of amino acids (from which all proteins

Enzyme Lab Using Jello
Enzyme Lab Using Jello INTRODUCTION: Enzymes are known as protein catalysts. The name protein catalyst suggests that most enzymes are made of proteins. A catalyst is a substance that speeds up chemical reactions without being consumed in the process. (Giuseppe, M 2002, p.69). After a reaction has been catalyzed, the catalyst can be used again to catalyze the same reaction. Enzymes reduce the activation energy (minimal energy) it takes for a reaction to take place.

Determining Optimum Environmental and Chemical Effects on Enzyme Kinetics
Abstract Enzymes, fundamental proteins that catalyze reactions by lowering activation energy, operate under kinetic principle and can react slower or faster with different ph and temperature levels. By finding this optimum temperature and pH through a process of spectrophotometery we can understand how many of the enzymes in our body function in different environments. I will examine a set of pH ranges and temperature ranges to find which one has the fastest reaction rate due

Activity of Enzymes Lab Report Introduction: Enzymes are catalysts that speed up chemical reactions in cells. They are important because they lower the activation energy so that certain reactions can take place faster. Enzymes are able to lower the activation energy to the extent that a small amount of heat can push reactants into a transition state.
