to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved

Purpose Use a standardized potassium permanganate solution to analyze an unknown iron solution by using redox titration. Theory Reduction-oxidation titration is an analytical method based on electrons transferring between an oxidizing agent and a reducing agent in solutions. Chemical analysis can be built on Redox titration if four criteria are met: a) The reaction is completed in a thermodynamically spontaneous condition. b) The reaction is fast enough to give an operational result instantly

Introduction A chromosome is a minuscule threadlike part of the nucleus and a structured DNA in the form of genes carrying hereditary information (Bridges‚ 1938). Endomitosis is the process of mitosis of chromosomes without undergoing nuclear or cellular division to increase cell volume. This results in a single nucleus having many copies of a single chromosome (Painter & Reindorp‚ 1940). In this experiment‚ Drosophila melanogaster is reared in specific conditions and its salivary gland extracted

The purpose of our experiment was to synthesize aspirin from acetyl anhydride‚ salicylic acid‚ and sulfuric acid. And then determine the relative purity of the synthesized sample. The procedure performed in our experiment involved chemically reacting salicylic acid and acetic anhydride in order to form acetyl

Isolation of exosomes from human serum The initial volume of serum for the experiments was 4 mL per sample. The samples were diluted with an equal volume of PBS (AppliChem‚ St. Louis‚ MO) to decrease the viscosity. The diluted serum samples were centrifuged at 2‚000×g for 10 min and 10‚000×g for 30 min at 4 °C to remove dead cells and cell debris. The supernatant was transferred into Ultra-ClearTM tubes (Beckman Coulter‚ Indianapolis‚ IN) and centrifuged at 100‚000×g using a Beckman Optima XL-70

ABSTRACT pH greatly affects the activity of enzymes. There is a point or pH level where maximum activity of enzyme can be achieved‚ this is called optimum pH. Invertase was extracted from yeast and used as the detanured enzymes. Two sets of six test tubes were each added with different
