    In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

    Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps

    This lab activity will go over environmental factors that affect the folded structure of proteins. We used a raw egg and noted the changes that happen when there were changes in temperature‚ pH levels‚ and salinity. Five eggs were cracked open and placed into different bowls with different solutions placed into each bowl. What we looked at was the process of denaturing of proteins seeing how it affected the composition of the raw egg between the yoke and white portion. My hypothesis for this experiment

    Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

    The properties of dibenzalacetone make it a great substance to be used when protecting the skin from the sun. In the experiment performed‚ dibenzalacetone was created from an aldol condensation of 2 portions of benzaldehyde and acetone in sodium hydroxide. The reaction that occurred in this experiment is known as a specific aldol condensation called Claisen-Schmidt. In the reaction‚ the carbonyl of benzaldehyde reacts quickly with the acetone anion to create a hydroxyketone that dehydrates in the
