Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food‚ for stimulating the brain‚ for providing cellular energy‚ and for repairing all tissues‚ organs‚ and cells. There are three types of enzymes: metabolic enzymes‚ digestive enzymes‚ and food enzymes. Metabolic enzymes catalyse‚ or spark‚ the reactions within the cells. The body’s organs‚ tissues and cells are run by metabolic enzymes. Without them our bodies

Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

2014 Due October 16‚ 2014 Anatomy and Physiology II Unit 5 Gas Exchange Explain how the gas laws and the properties of gases affect the gas exchange between the lung‚ blood‚ and tissues. The major function of the respiratory system is to provide the body with oxygen and rid the body of carbon dioxide. Gas exchange occurs between blood and alveolar air (external respiration) and between blood and tissues (internal respiration).Gas exchange process depends on properties of gasses. Based upon

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Introduction: Enzymes are biological catalysts that permit cells to carry out the many functions that are required in a living system. Every enzyme has a specific substrate and a specific function. Enzymes alter substrates one of three ways: by adding something to the substrate‚ removing something from the substrate‚ or by changing its conformation‚ otherwise known as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the
