    Transpiration Lab Write-up. Introduction Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference, water vapor diffuses from the spaces of the leaf, through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less...

    Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The...

Activation energy is known as the amount of energy needed to push the reactants over an energy barrier, so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction, the enzyme binds to its substrate, which is the reactant an enzyme acts on. In the reactions, the enzymes are very specific...

Many factors in a cell’s environment affect the action of an enzyme. In this investigation, you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials ...

  • Enzyme Lab Report

    Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize, bind, and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such...

    Kinesiology 303 Lab Vertical and Horizontal Power Lab Write up Introduction: Running and jumping competitions have taken place for centuries, dating as far back as the first Olympian games. These physical competitions measured individual’s prowess, but also competing for power to rule or show their masculinity. Today, in modern times, this is synonymous to individuals who are judged on their highest jump and fastest 40-yard dash time as part of the National Football League draft, which combine...
