In Class Mar. 21: a rendition of the plasma membrane

For this activity, we’ll need 8 volunteers:

  • 6 of you will each be a phospholipid with your hydrophobic arms held out in front of your hydrophilic torso;
  • 2 of you will each be a protein with your hydrophilic arms extended out to the sides of your hydrophobic torso.

And you’ll do two things:

  1.  First, phospholipids, how will you arrange yourselves together if you’re in an aqueous environment (i.e. surrounded by water molecules)?
  2. Proteins, how will you situate yourselves relative to these now nicely arranged phospholipids?

Did this work out as planned? Hit the “Read More” link to find out.
