Sequence III: Genes for Virulence Factors that appeared during the Seventh Pandemic Sequence IV: Genes for Exotoxins produced by numerous other Bacteria It takes a while for the Caffeine to walk down the Jetway and be welcomed aboard your Brain and for you to realize that the Identity of these DNA Sequences is as follows: A. I = CTX φ II = VPI -- or possibly -- VPI φ III = VSP-1 and VSP-2 IV = RTX ____________________________ B. I = VPI φ II = CTX -- or possibly -- CTX φ III = VSP-1 and VSP-2 IV = SXT ____________________________ C. I = VPI -- or possibly -- VPI φ II = VSP-1 and VSP-2 III = SXT IV = CTX φ ____________________________ D. I = RTX II = VSP-1 and VSP-2 III = VPI -- or possibly -- VPI φ IV = CTX φ

MIC 101 Exam 2 Page 31 47. The severe Diarrhea that is the most characteristic Symptom of Cholera occurs when -- A. • The A Subunit of Cholera Exotoxin (MW = 17.6 kD) enters Intestinal Epithelial Cells and is cleaved to a Fragment called A 1 . • A 1 binds to Adenylate Cyclase, inhibiting the Synthesis of Cyclic AMP • Low Levels of Cyclic AMP result in -- - Hypersecretion of Water and Sodium Ions - Inhibition of Absorption of Chloride Ions. ____________________________ B • The B Subunit of Cholera Endotoxin (MW = 11.6 kD) enters Intestinal Epithelial Cells. • The B Subunit binds to Adenylate Cyclase, inhibiting the Synthesis of Cyclic AMP • Low Levels of Cyclic Amp result in -- - Hypersecretion of Sodium Ions - Inhibition of Absorption of Chloride Ions. ____________________________ C. • The A Subunit of Cholera Enterotoxin (MW = 17.6 kD) enters Intestinal Epithelial Cells and is cleaved to a Fragment called A 1 . • A 1 binds to Adenylate Cyclase, inducing High Levels of Cyclic AMP • High Levels of Cyclic AMP result in -- - Hypersecretion of Water and Chloride Ions - Inhibition of Absorption of Sodium Ions. ____________________________ D. • The B Subunit of Cholera Endotoxin (MW = 11.7 kD) enters Intestinal Epithelial Cells. • The B Subunit binds to Adenylate Cyclase, inducing High Levels of Cyclic AMP • High Levels of Cyclic Amp result in -- - Hypersecretion of Water and Chloride Ions - Inhibition of Absorption of Chloride Ions.

MIC 101 Exam 2 Page 32 48. How does Oral Rehydration Therapy (ORT) work? A. • The Primary Ingredient in each Pre-Measured ORT Packet is 20 Grams (4 Tablespoons) of Glucose (C 6 H 12 O 6 ) • Glucose Uptake in Intestinal Epithelial Cells remains Intact. • The Uptake of Glucose in ORT enhances the Uptake of Sodium and this enhanced Sodium Uptake allows the Uptake of Water. ____________________________ B. • The Primary Ingredient in each Pre-Measured ORT Packet is 15 Grams (1/4 Teaspoon) of Potassium Chloride (KCl) • Potassium Uptake in Intestinal Epithelial Cells remains Intact • The Uptake of Potassium in ORT raises cAMP Levels and eliminates the Hypersecretion of Water and Chloride Ions. ____________________________ C. • The Primary Ingredient in each Pre-Measured ORT Packet is 35 Grams (1/2 Teaspoon) of Salt (NaCl) • Sodium Uptake in Intestinal Epithelial Cells remains Intact • The Uptake of Sodium in ORT lowers cAMP Levels and eliminates the Hypersecretion of Water and Chloride Ions.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
