Proteins are made up of long chains of amino acids‚ just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiary structure is formed by even more folding and joining of the chains to make a globular mass or fibrous mass. An example of this would be a carrier protein. Proteins are needed for many things they are needed in our diet for growth and repair of cells

1. Gather all the equipments needed. 2. Measure 50ml of HCL in a 250 ml measuring cylinder and pour it into a flask‚ then measure 50ml of HCL again and pour it into the second flask. 3. Measure the 50ml of KOH in a measuring cylinder. Repeat it again in another measuring cylinder. 4. Attach both of the burette clamps to both of the burette stands and clamp the burette at a certain level so that it can fit a flask underneath. 5. Then‚ place a funnel on top of each burette. 6. Place a flask underneath

this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded into a unique shape. That shape permits the enzyme to carry out specific chemical reactions - an enzyme acts as

You MUST include diagrams to aid in your explanations Messenger ribonucleic acid (mRNA)‚ which is like DNA has a unique code that is in a number of different patterns‚ which engages in the sending messages to the structures within the cell. Transfer Ribonucleic Acid (tRNA) is a nucleic acid‚ which is involved in the process of protein synthesis inside the cell. When mRNA is in

General Biology I Spring Semester 2013 Lab Report Name: Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme
Premium Enzyme Catalase PH
Factors Affecting the rate of Hydrogen Peroxide degradation using Catalase Introduction An enzyme is a globular protein which functions as a catalyst that speeds up the rate of a reaction without being consumed in the reaction. An enzyme-catalyzed reaction occurs when a substance called the substrate binds onto the active site of the enzyme. This joining allows for a reduction in the activation energy and the reduction in activation energy helps the reaction to occur at a quicker rate. Enzyme

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction
