Here's an update copy of UMUC Biology 102/103;Lab 4: Enzymes 2014.;I would like it finished and added to the site.;Attachment Preview;Lab4AnswerForm.rtf Download Attachment;TY PE Y OUR FULL NAME;UMUC Biology 102/103;Lab 4: Enzymes;INSTRUCTIONS;On your own and without assistance, complete this Lab4AnswerForm electronically;and submit it via Assignments by the date listed on your Course Schedule (under;Content - Syllabus). NOTE: The Assignment tab closes promptly @ 11:59 PM ET;and will not be available even a minute past the deadline. Save your;Lab4AnswerForm in the following format: LastName_Lab4 (e.g., Smith_Lab4).;I will be posting feedback under a private Lab 4 Feedback group in the Discussions;after I have graded all the labs. You will gain access to the private Lab 4 area if you;submit a complete lab on time.;You must submit your document in a Word (.doc or.docx) or Rich Text Format (.rtf);to receive credit. I cannot open Works or WordPerfect files.;Experiment 1: Enzymes in;Food (15 pts);Table 1: Substance vs. Starch;Presence;Substance;Resulting Color;Presence of Starch?;Positive Control: Starch;Negative Control: Student Must Select;Food Product;Food Product;Saliva;Post-Lab Questions;1. What were your controls for this experiment? What did they demonstrate? Why was saliva;included in this experiment?;2. What is the function of amylase? What does amylase do to starch?;3. Which of the foods that you tested contained amylase? Which did not? What experimental;evidence supports your claim?;4. Saliva does not contain amylase until babies are two months old. How could this affect an;infants digestive requirements?;5. Digestive enzymes in the gut include proteases, which digest proteins. Why dont these;enzymes digest the stomach and small intestine, which are partially composed of protein?;Experiment 2: Effect of temperature on enzyme activity (15 pts);Table 2: Record the effect of temperature on the production of gas;Tube;Temperature;(C);Balloon;Circumference;(Uninflated in cm);Balloon Circumference;(Inflated in cm);1 (cold);2 (room temp);3 (hot);Post-Lab Questions;1. What is the enzyme in this experiment? What is the substrate?;2. What is the independent (IV) and dependent (DV) variables in this study?;3. How does temperature affect enzyme function?;4. How can enzyme activity be increased?;5. In general, how would an increase in substrate alter enzyme activity? Draw or;insert a graph to illustrate this relationship.;6. Draw a graph using balloon diameter vs. temperature. You may use Excel, then;Insert the graph, or use another drawing program. You may also draw it neatly;by hand and scan your drawing. You would need to insert the scanned jpg image;here, in that case. What is the correlation shown on your graph?;7. Design an experiment to determine the optimal temperature for enzyme function;complete with controls. Be sure to state your hypothesis, describe your design;dissect your variables (IV/DV), and predict your results. When you describe your;design, be sure to explain where you will find the enzymes for this experiment;and what substrate you will use.
