Clathrin Samenvattingen, Aantekeningen en Examens

Question 1 2.5 / 2.5 pts Indicate whether each of the following descriptions better applies to COPI- (1), COPII- (2), or clathrin- (3) coated vesicles. Your answer would be a four-digit number composed of digits 1 to 3 only, e.g. 1322. ( ) They mediate transport from the ER to the cis Golgi network. ( ) Their coat protein forms a three-legged structure called a triskelion. ( ) They are pinched off from their donor compartment by a dynamin collar. ( ) They are involved in retrograde trans...

what did multicellularity lead to? - need for a highly coordinated system to regulate and integrate the physiological functioning of different cells within one organism mode of hormonal communication? - chemical signalling examples of types on triggers? - location, visual, language, sound, gesture visual trigger - circadian rhythms location trigger - sender to receiver language trigger - chemical signalling gesture trigger - social, stress, sex sound trigger - lactation what is the unit...

Deze gedetailleerde samenvatting behandelt alles wat aan bod is gekomen tijdens de hoorcolleges en werkcolleges van week 4 t/m 7 (celbiologie, metabolisme en kanker) van de cursus Moleculair Biologie van de Cel aan de Universiteit Utrecht (BMW33416). Daarnaast zijn de corresponderende hoofdstukken uit het boek Molecular Biology of the Cell (6th edition Alberts) ook in de samenvatting opgenomen. Hierdoor bevat het alle informatie die nodig is voor het 2e deeltentamen.

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...

Bio 180 Exam 5 BYUI Questions and Answers Already Passed Lipid-soluble signal molecules, such as testosterone, cross the membranes of all cells but affect only target cells because: Intracellular receptors are present only in target cells. Which type of receptor is most associated with metabolism, cell growth, and cell division? Tyrosine kinase receptors Which type of receptor is a dimer that when bound to the proper ligand autophosphorylates? Tyrosine kinase receptors A drug designed to inh...
