RESEARCH METHODOLOGY (PSH IV) TERM PAPER SCIENTIFIC DOCUMENTATION IN RESEARCH ARDEEP PANESAR PSYCHOLOGY (HONS.) II YEAR 52 A Scientific Research is a systematic‚ controlled‚ empirical‚ and critical investigation of hypothetical propositions about the presumed relations among natural phenomena. An important step in research is To Publish good research data correctly. Reporting The Research is essential for the progress of science and also to maintain the self-correcting nature of science

Sharnela Kamil Sahidjuan BSN-1A Reaction paper The world‚ as we all know is going into high technological advances and its going real fast! Things that we never imagine possible is now a reality. Babies formed out of experiments‚ genetic diseases being corrected‚ solutions are being uncovered for medical problems we never thought we could solve‚ new ways to treat diseases and making real live human body organs‚ in years time the idea of human cloning may be a shocking

Discussion The primary purpose of this experiment was to determine the optimum temperature range for the activity of the enzyme lactase. Extreme temperatures can have a detrimental effect on enzymes; very hot temperatures can cause the denaturation in the enzyme‚ which is the loss of protein structure. This causes a change in the shape of the enzyme leading to its inability to perform its function. As previously stated‚ the alternate hypothesis read: the optimal temperature range for lactase activity

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

Effects of Substrate Concentration‚ Reaction Time and Enzyme Concentration on Enzyme Reactions Corey von Ellm-St. Croix Rachael Kwan ID#: 20427841 Matthew Hrycyshyn & Saeideh Mayanloo Biol 130L‚ Section 017 Wednesday‚ 9:30am-12:20pm‚ 151 November 09‚ 2011 A living system controls its activity through enzymes. Enzymes are made from hundreds or even thousands of amino acids connected in a very unique and specific order. Almost all enzymes are proteins‚ except for ribozymes. The chain of amino

Enzymes are biological molecules (proteins) that act as a catalyst and help complex reactions occur everywhere in life‚ for example a piece of steak that is being digested into energy. Molecules found at the beginning of the process are called substrates‚ and these enzymes exchange them into differing molecules known as products. Nearly all-metabolic processes in a cell need enzymes in order to function at rates that are fast enough to sustain existence. Those who are lactose intolerant are simply

This experiment is to determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments

The environmental factors that effected the rate of enzyme reactions were the enzyme concentration‚ pH‚ and temperature. These environmental factors help enzymes break down the poisonous chemicals into harmless substance. When we tested the liver with 2ml of hydrogen peroxide for a normal reaction it showed that it was exothermic. We added more hydrogen peroxide and the reaction rate of the liver was 3. We learned that the catalase is reusable because the liver reacted both times when we put in

Biology‚ Section G 27 September 2013 Experiment 5.3 Title: The Fragility of an Enzyme Purpose: To see how easily enzyme function can be destroyed. Hypothesis: I think that the bowl with only Jell-O will set as will the bowl with heated pineapple but the Jell-O with fresh‚ uncooked pineapple will not set. Materials: Part of a fresh pineapple A blender or a fine cheese grater 3 small bowls A small box of Jell-O Pot Stove Refrigerator 2 tablespoons Procedure: 1. Cut the pineapple
