Cell membrane Correct Answer Phosphatidylcholine and sphingomyelin on EC side Phosphatidylethanolamine and phosphatidylserine on inside Increase in cholesterol => decrease in fluidity/permeability In some cells, covered by carb-rich glycocalyx Receptor-mediated endocytosis => both receptor and ligand get ingested by clathrin-coated vesicle Disorders of transport Correct Answer CF: defect in CTFR => salty sweat and thick mucus Cystinuria: inability to reabsorb cys in kidneys =&gt...

BIO 2120 Exam 3 - Questions and Answers What is the key to maintaining the functional organization of a cell? The selectivity of vesicular transport- vesicles must recognize and fuse only with the appropriate target membrane Transport vesicles from the ER are coated with ___. Cytosolic coat proteins- coats assemble as the vesicle buds off and are removed in the cytosol before it reaches its target. The vesicles fuse with the target membrane, empty their cargo, and their membrane proteins diffus...
