Cell membrane - 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 - CF: defect in CTFR => salty sweat and thick mucus Cystinuria: inability to reabsorb cys in kidneys => kidney stones Hereditar...

IB Biology B2.1 - Membranes and Membranes Transport Questions And Answers Rated A+ Why do cells need membranes? • To distinguish itself from its surroundings • To be selective about what gets in and out How do lipids assemble to form a semipermeable membrane? Being cylindrical, phospholipid molecules spontaneously form bilayers in aqueous environments. In this energetically most-favorable arrangement, the hydrophilic heads face the water at each surface of the bilayer, and the ...

BIOL 1P91 – Final EXAM .OVER 280 QUESTIONS WITH VERIFIED CORRECT ANSWERS Holds the cell together and controls what goes in and out - ANSWER cell membrane separates cell contents from the surrounding environment - ANSWER plasma membrane uptake and export of ions and molecules, cell compartmentalization, protein storing, anchoring cytoskeleton, production of ATP and NADPH, cell signalling, cell and nuclear division, and adhesion of cells to each other and to the extracellular...

What are sphingomyelins? - Sphingolipids where the head group is phosphocholine or phosphoethanolamine. What prevents cells from actually swelling? - It is effectively impossible for sodium to enter the cell (due to pump and lack of sodium channels). There is a high sodium ion concentration outside the cell which prevents water from entering in the cell Why would cells have a tendency to swell? - Because cytoplasm contains negatively charged proteins that cannot exit, so cells naturally ga...
