Neurophysiology Lab Report Anatomy & Physiology Lab Report Exercise 3 Activities 1-4‚ 8 By Laurence Blake 2/27/12 A. Objective I. Activity 1-4: Eliciting a Nerve Impulse • Investigate what kinds of stimuli stimulate action potential. II. Activity 8: Nerve Conduction Velocity • Determine and compare the conduction velocities of different types of nerves. B. Introduction I. Activity 1-4: Eliciting a Nerve Impulse • In this experiment‚ we

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence of

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can

01:447:390 General Microbiology TA: Jennifer Goff ABSTRACT This report delineates how unknown #405 was identified as Proteus vulgaris out of a possible seven species of Enterobacteriaceae by applying various tests that are able to distinguish between members of the family. Inevitably‚ the results for many tests are identical across multiple species‚ which is expected due to the organisms’ evolutionary relatedness. However‚ some tests are specific to select organisms and contribute to the basis on

Fermentation Lab Report Hannah Newman Fermentation is the chemical process converting sugar to gases and occurs in yeast and bacteria. In the experiment we conducted‚ we used sucrose and yeast and measured the fermentation carbon dioxide formation. The factors affecting fermentation that we tested in this experiment were temperature and the effect of a disinfectant. We measured the fermentation carbon dioxide formation by using a ruler and measuring the amount of bubbles in the tube that were

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

series of tests. First was the glucose‚ lactose‚ and sucrose test. Through these three tests‚ I was able to detect the ability of the microorganism to ferment a specific carbohydrate. Fermentation reactions are observed by the color change in pH. In class‚ we used phenol red as the pH indicator and the result was a yellow color which indicated that enough acids products have been produced by fermentation (Phenol Red Carbohydrate Fermentation Broth lab handout). Next was the catalase test. After adding

The Ouchterlony procedure is what will be used in this lab to detect nature of the antibody interaction. The orientations of the band will provide more information about the interaction of antibody and antigen

results in a linear graph allowing us to determine the maximum velocity at which it can catalyze the reaction. Therefore‚ it will be presumed that the result of this experiment by isolating the polyphenol oxidase within the potato extract through the oxidation of 5mM dopa solution with highly concentrated enzymatic preparation of polyphenol oxidase with a buffer as the diluent will indicate a rapid increase in the rate of the reaction as well as the amount of activity present in the potato extract.
