Temperature Effects in Enzyme Activity
Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins, which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape, which makes enzymes different from other proteins. A common enzyme that we have is catalase, which breaks down hydrogen

The Effect of Ph and Enzyme Concentration on Enzyme Activity
1. The Effect of pH and Enzyme Concentration on Enzyme Activity 2. Abstract Enzymes help many chemical reactions to occur in living organisms. Enzymes are very specific molecules, each enzyme has a certain type of active site necessary for the reaction to happen. The reactions are very sensitive to changes in pH and enzyme concentration. Changes in the pH can drastically affect the solubility, structure and stability of the enzyme while the enzyme concentration correlates

Effects of Activators and Ethanol on Fermentation Rates
Effects of Activators and Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate, and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4, pyruvate, ethanol, and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate

Factors That Determine the Currency Exchange Rates
Factors that Determine the Currency Exchange Rates Exchange rate is often referred to as the nominal exchange rate. It is defined as the rate at which one currency can be converted, or 'exchanged', into another currency. For example, the pound is currently worth about 1.824 US dollars. One pound can be converted into 1.824 dollars. This is the exchange rate between the pound and the dollar. There are four types of currencies can be operated,

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

Amylase Activity in Different Environmental Factor
The Effects of Temperature, Concentration and pH on the Enzymatic Activity of Introduction Enzymes are globular proteins that act as biological catalysts for biochemical processes within a living cell. Enzymes increase reaction rate by lowering the activation energy of the reaction, however they are not consumed. An enzyme is present as both a reactant and a product in a reaction. Substrates are the reactants for an enzyme and since enzymes have such a high specificity,
