Principles of Biology Lab Exercise Enzymes: Catalysts of Life Instructor: Professor Alcendor By Shahid Rana Date: March 7th‚ 2013 Abstract: In this experiment we have demonstrated the function of enzymes. The whole experiment was devoted to understand how enzymes work as a catalysts and increase the chemical reaction without being used themselves. In general‚ enzymes are proteins that function as biological catalysts. These enzymes adhere to lower to amount of energy required for

– Restriction Enzyme Digestion To begin this experiment‚ the DNA molecules must be cut into smaller fragments with distinct enzymes called Restriction Enzymes through a process called Restriction Enzyme Digestion. Four microtest tubes were labeled 1 through 4 and added 10 µl of Enzyme Reaction Buffer to each of the four reaction tubes using a micropipette. DNA‚ and Enzyme 1 and 2‚ were then added to the reaction tubes using a new micropipette tip for each transfer of DNA and enzyme (refer to figure

Literary Elements Plot Plot is the sequence of related events in a work of literature. It may be simple or complex‚ and it includes what characters do‚ think‚ and say. The word first used by Aristotle for plot in Poetics was mythos (origin of the word myth). According to Aristotle‚ plot was the "soul of tragedy": its "first principle." The general structure of plot is as follows: Exposition: gives information about settings and characters Conflict: struggle between characters or forces

Part B: Practical Report The Effect of Temperature on Enzyme Activity Aim: To investigate how temperature effects the enzyme catalase. Hypothesis: If the temperature of water is increased then the enzyme will react quicker to form oxygen and water‚ when compared to cold water. Purpose: To design and conduct a plan of a practical about the effects of temperature on enzymatic activity with a partner. Introduction: An enzyme is a protein‚ which speeds up a specific chemical reaction without altering

Enzymes Abstract: The following 2 labs experimented the more enzymes and substrates added to the concentration will effect the reaction rate. Our second lab‚ we tested enzyme and substrate concentrations to determine the increase of temperature and inhibitor. The enzyme source used in both labs was peroxide‚ guaiacol is used as a substrate for peroxide. We used Guaiacol‚ turnip extract‚ peroxide and distilled water for enzyme and substrate concentration. In the second lab we used the same substances

DIGESTIVE ENZYMES AND THEIR FUNCTIONS Mouth -the oral cavity or the mouth contains salivary glands that secrete a wide range of enzymes to aid the first step of metabolism of food. The salivary gland secretes the enzyme lysozyme which has an antibacterial action. The enzymes secreted by the mouth mainly provide protection against bacteria. Betaine helps to maintain a fluid balance inside the mouth. The lists of digestive enzymes secreted by the oral cavity are mentioned in the table. Enzymes | Function
