BIOLOGY 1 LAB

29 Jul BIOLOGY 1 LAB

Must include all sections specified below. Each section should have a heading.

· Title your paper appropriately.

· This paper should be written from the perspective of a researcher writing up an experiment, notas a student doing an assignment.

· Use campus data, not just your group’s or section’s results.

 

Content

· Abstract should consist of a brief statement of purpose and results of study.

· Introduction should include more in-depth discussion of purpose, pertinent background information, and a statement of the hypothesis (state expectations or predictions)

· Materials and methods should restate “procedure” from lab book, in pastDo not quote from it. This should be in paragraph form, as should the entire paper.

· Results should include a discussion of the statistical results and what they mean.

· Conclusions should clearly state whether hypothesis was supported or not. Also WHY did we get the results we did, WHAT does it mean to the larger world?

· Works cited should include at least two NO “.com” or “.net” internet sites, including Wikipedia.  These can be used to FIND primary sources (journal articles, .edu sites, etc).  Any cited article must have an author’s name, not just a web site.

 

Neatness and Writing

· Type, proofread, and check the spelling and grammar before you turn this assignment in.

· Remember that this is a formal paper and the writing should reflect that.

· There is no minimum page requirement, but generally fewer than 3 pages indicates a section was left out or was incomplete.

· Staple the pages together at upper left corner; do not include a cover sheet or other binding.

olecule that acts as a catalyst for a chemical reaction. It acts by lowering the activationenergy needed for reactions to progress in cells. The reaction occurs without the presence of the

enzyme, but at a much slower rate. Enzymes are almost all protein molecules.2. Activation Energy: The minimum energy needed for a chemical reaction to occur.3. Substrate(s): The reactant(s) of the reaction that is/are bound by the enzyme4. Active Site: The region of the enzyme where substrates bind. This site is flexible, and can reform toassist with the catalysis of the reaction of the substrates. Once the substrates have formedproduct(s) and have become unbound, the active site can return to its original shape. 8.1 The Effect of Temperature on Enzymatic Activity

IntroductionThe activity of every enzyme can be affected by alterations to its environment. In the following experiment,you will test the effects that changes in temperature have on lactase. At extremely low temperatures,molecules move so slowly that reaction rates can be hampered, even though the enzyme is still properlyfolded and active. At extremely high temperatures, bonds and interactions that exist between the aminoacid side chains (R groups) in an enzyme become disrupted. The result is that the enzyme unfolds, losing its3-dimensional shape, and becomes inactive. This process of a protein losing structure and functionality iscalled protein denaturation. Although temperature can have negative effects on enzymatic activity, there is
