Research Paper First and foremost‚ the freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point

The activity of an Enzyme is affected by its environmental conditions and changing these factors can alter the overall rate of the reaction. Reaction rates are influenced by external factors such as pH‚ temperature and salt concentration. Different enzymes have different optimum temperatures in which they are most efficient and different pH levels which is ideal for their formation of enzyme-substrate complexes. As the temperature increases‚ there is more movement of molecules and more random collisions

The purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions;

On Saturday‚ December 2nd‚ I saw the Live Newspaper Production of: BOILING POINT! Water‚ Politics‚ and Power. Boiling Point is production directed by Tom Harryman that gave a voice‚ while using satire‚ to show the flaws of how people of power in America deal with problems revolved around water. In this essay‚ I will analyze the audience‚ design‚ theme‚ acting‚ and the spectacle of the play. The audience had a mixed group of people. Even though I did not see anyone under that age of 17‚ I heard a

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

The Effect of Substrate Concentration on Initial Reaction Rate The purpose of this study is to identify the relationship between substrate concentration and initial reaction rate provided that substrate concentration is much greater than enzyme concentration. Enzymes are essential to life as they are required for many vital metabolic reactions to occur. To adequately explain the properties of enzymes‚ it is assumed that an enzyme-controlled reaction takes place through an enzyme-substrate
