Document Summary
Block 2 - lecture 3 - cellular and molecular strategies of. Compare and contrast the paracellular vs. transcellular pathways of substrate flux across an epithelial cell layer a. Discuss the role of the tight junction and the basis of its permselectivity in the context of the structure and function of epithelia. List four secretagogues that stimulates secretion of digestive proteins by pancreatic acinar cells a. Describe the regulatory pathway associated with cck and ach regulation of pancreatic protein secretion. Describe the basic mechanism of stimulus secretion coupling (ssc), including the general role of. Draw a schematic diagram that summarizes the relationship between the transport processes responsible for isotonic secretion of salt and water by the pancreatic acinar cells. The basolateral compartment is exposed to the interstitial fluid (blood stream) and the apical side is exposed to a compartment that is continuous with the outside world. Glucose is transported transcellularly (crossing both apical and basolateral membrane).
