what membrane proteins that forms a pore through the plasma membrane

Homework Answers

Answer #1

Membrane proteins are very essential for proper functioning of the cells.

  • Intrinsic proteins: are embedded in phospholipid bilayer.
  • Transport proteins: are associated with transport of substances across the membrane.
  • Enzymes: perform several tasks due to their enzymatic effect.
  • Signal transduction proteins : They lie outside the cell membrane. They are associated with metabotropic receptors (G-protein coupled receptors). They perform various cellular events.
  • Recognition proteins :They act as identification tags.

The nuclear pore complex forms a large pore with a gel-like barrier of proteins with short, repetitive domains called FG domains due to the presence of phenylalanine and glycine. How do these repeat domains contribute to the gel-like barrier? Generally, how do nuclear import receptors disrupt and traverse this barrier? (This is just focusing on the nuclear import receptors and the NPC proteins of the pore.)

A membrane is being engineered for filtering proteins. Its pores have charged surfaces, so some of the sieving effect of the membrane comes from the electrostatic repulsion of the proteins from the walls of the pore. Consider the membrane pore to be a parallel slit 10 nm in width, and the surface potential to be 50 mV. Assume the potential at the midplane to be low, and calculate it for the case of 15 mM ionic strength (coming from a...

Consider a hypothetical cell whose plasma membrane is impermeant to everything. The membrane is studded with channel proteins for Ca2+, but these channels are initially closed. The concentration of Ca2+ outside the cell is 100 mM and the concentration of Ca2+ inside the cell is 1 mM. Initally, the membrane potential is 0 mV. a) In response to a signal molecule, all of the Ca2+ channel proteins suddenly become open. In which direction is there a net flow of Ca2+?...
