Enzymes Enzymes are… * Biological catalysts Lower the energy level needed for a biochemical reaction to occur. This energy level is called activation energy. * Proteins Polypeptide chains made up of 100’s-1000’s of amino acids in a specific sequence. * Do not get “used up” in a reaction The number of “uses” of an enzyme depends on the enzyme. * Work more efficiently at certain optimum temperatures. * They are “reaction-specific”. Each enzyme is included in one reaction.

Date: 14th-15th October Title: The effect of the concentration of hydrogen peroxide on catalase Aim: to examine how the concentration of the hydrogen peroxide affects the rate of reaction Hypothesis: The substrate concentration will determine the rate of reaction. The reaction will increase as the concentration increases‚ but from a certain concentration‚ the rate will maintain the same rate Materials: 3% hydrogen peroxide 6% hydrogen peroxide catalase round metal basin measuring cylinder

that being over 2.5% of the world’s population‚ it is a history that we hope to never repeat; to govern this‚ it is vital that we identify the causes of the war‚ however difficult the task may be. Many historians have discussed the possibilities that three of the major causes of World War II might have been Treaty of Versailles‚ the struggle during the Great Depression‚ and movement towards‚ and the ultimate failure of Appeasement; these ideas are highly plausible and the topic itself has been widely

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

MAIN EFFECTS AND INTERACTION EFFECTS OF FACTORIAL DESIGN Two kinds of information can be gleaned from a factorial design. The first piece of information gained from a factorial design is whether there are any main effects. A main effect is an effect of a single independent variable. In our design with two independent variables‚ two main effects are possible: an effect of word type and an effect of rehearsal type. In other words‚ there can be as many main effects as there are independent variables
