    BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

    Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a
