Ellen Grant Honors Bio I Organic Compounds Problems and Objectives: The purpose of this lab was to select the suitable test for an organic molecule and define the safe process for that test. An organic molecule is normally found in or produced by living systems. (Unknown Author‚ 2014‚ www.biology-online.org/organic_molecule)In this lab one was supposed to infer the results of the test and be able to identify if major biomolecules are present. You were to analyze a variety of tests including

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Unit 10: Biological Molecules and Metabolic Pathways C: Explore the factors that can affect the pathways and the rate of photosynthesis in plants The following report is about the factors which can affect the pathways and the the rate of photosynthesis in plants. This report will cover what photosynthesis is ‚ the factors which may affect photosynthesis in working poorly‚ light independant and dependant reaction. An investigation will be carried out which will include the factors that affect photosynthesis

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

LAB EXERCISE: Diffusion and Osmosis Laboratory Objectives After completing this lab topic‚ you should be able to: 1. Describe the mechanism of diffusion at the molecular level. 2. List several factors that influence the rate of diffusion. 3. Explain why diffusion is important to cells. 4. Describe a selectively permeable membrane‚ and explain its role in osmosis. 5. Define hypotonic‚ hypertonic‚ and isotonic in terms of relative concentrations of osmotically active substances. 6. Discuss
