of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips * 20 test tubes

pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

sucrose‚ 1%lactose‚ 1% glycogen‚ 1% starch‚ protein‚ beer‚ distilled water and an unknown solution (test tube: 300). The iodine test for starch was to test how would starch reacted if we put iodine in it. The color of starch before the test was clear. The color of the iodine was brown. When you added iodine into starch‚ the result was the starch solution turned dark blue. Starch had a positive result is because of the complex of iodine stuck inside the amylase coil which produced a characteristic

the gastrointestinal tract plus the accessory organs of digestion (the tongue‚ salivary glands‚ pancreas‚ liver‚ and gallbladder).[1] In this system‚ the process of digestion has many stages‚ the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components‚ until they can be absorbed and assimilated into the body. Chewing‚ in which food is mixed with saliva begins the process of digestion. This produces a bolus which can be swallowed down the esophagus

Anaerobic digestion Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚
