The purpose of the enzyme lab conducted was to observe the chemical composition of cells. In order to do so we tested for the presence of organic molecules. Molecules are what forms when atoms bond together. Organic molecules of cells include proteins, carbohydrates, and lipids, which are composed of smaller molecules known as monomers and polymers. Polymers are joined monomers. A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis

Lab Report #2 Name: Lab: #9 Enzymes – Experiment #4 Due date: Purpose The purpose of the experiment is to compare and examine the effect of substrate concentration on catalase activity. Introduction All chemical reactions require a catalyst. A type of catalyst that exists is an enzyme, which acts to bring out a specific biochemical reaction. At all times, all work inside a cell is being performed by enzymes (Brian, 2000). The purpose of an enzyme is to help the cell carry out reactions

Writing a Laboratory Report The final step in any scientific investigation is to communicate your findings. This is done in the form of a laboratory report or, for more involved studies, a scientific paper. There is a standard format that is generally used for both lab reports and papers. The sections are: * Title * Introduction * Materials and Methods * Results * Discussion * Literature Cited Title: The title should be brief, descriptive, and should clearly

Guided Inquiry Laboratory Procedure: CAN the METTLE of METAL be IMPROVED? OBJECTIVE: You will conduct an experiment to investigate the effect of heating, quenching, and tempering on metals and gather evidence to provide an explanation for the phenomenon observed. QUESTION: What effect will annealing (strong heating followed by slow cooling), quenching (strong heating followed by quick cooling), or tempering (strong heating followed by quick cooling, then strong heating and slow cooling) have

Lab Report 2 – Titration CHEM1903 – Chemistry 1A (SSP) Michael West (305159240) 1. Experiment 2.2 – Titrimetric determination of the molecular mass of an organic acid Method An unknown organic acid was supplied in solid form. The acid was known to be diprotic and had the reference number 19. Using an analytical balance, 1.5397 g of the acid were weighed out, and made up with deionised water into 250 mL of solution. 25 mL of the acid solution was added to a conical flask with phenolphthalein
