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.

Procedures for Part A: For Activity A‚ we first tested enzyme activity. First‚ we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then‚ we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that‚ we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that‚ we placed the test tube filled

Module 10 Free Response Kyle Richardson Psychodynamic: One advantage of psychodynamic therapy is the relationship that is formed between the psychologist and the patient. The patient is able to form trust in the psychologist which makes it easier for them to talk about their problems. Another advantage is the ability for the psychologist to give a human opinion. They can tell the client what they think is best for them specific to the client’s needs. Client-centered: The advantage of this is

independence‚ that they can think freely‚ choose freely‚ and express themselves freely. This all is connected to the idea of free will that many believe is what makes us human. Many people cannot‚ however‚ define free will. There is always the feeling that one can do whatever he/she wants. That is probably why this idea is such a pleasing concept. There is just one serious flaw in the free will concept. People cannot determine everything; there are some things‚ even before one is born‚ that determines who

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;
