Question

Use the image below to help answer question 16 Intestinal Lumen Epithelial Cell Apical Membrane 16. Based on what you know about transepithelial transport in the intestine, how does "Olsonium" move across the apical and basolateral membrane? A. Active transport through both the apical and basolateral sides of the epithelial cell B. Facilitated diffusion on the apical side and simple diffusion on the basolateral side C. Secondary active transport on the apical side and facilitated diffusion on the basolateral side D. Simple diffusion on the apical side and primary active transport on the basolateral side 17. Heart cells undergo intense mechanical strain as the heart contracts and relaxes. To prevent tearing of the tissue, Heart Cell A' attaches to Heart Cell B' through which of the following mechanisms? A. Tight junctions B. Intracellular signaling pathways C. Gap junctions 18. A doctor administers an IV (intravenous) injection of saline into a patient who is severely dehydrated. The saline (300mOsm NaCI) given will help to replenish fluids in which fluid compartments within the body? A. Only the intracellular compartment B. Only the interstitial fluid C. Both the interstitial fluid and intracellular fluid compartments D. Both the plasma and interstitial fluid compartments 19. One common symptom of patients suffering from liver failure is hypoalbuminemia (lovw albumin production). Which of the following symptoms would you expect to see in a patient with hypoalbumineamia? A. Decreased capillary filtration B. Increased capillary reabsorption C. Interstitial fluid accumulation D. Increased oncotic pressure 20. True or False: During hypertonic dehydration cell size can decrease

Explanation / Answer

D. The transport of Olsonium moves across the apical and basolateral side by the process of simple diffusion. The simple diffusion of olsonium occurs without aid of any intercellular or membrane protein. As the image itself shows no involvement of cellular or membrane proteins to carry out the process of transport.
