• On the outside of the membrane

• On the inside of the membrane

• Embedded part of the way into the membrane

• Embedded the whole way through the membrane

• All of the above

Where can PROTEINS be found when part of a plasma membrane?

What is the "big idea" of the fluid mosaic model of plasma membranes?

• the plasma membrane creates a specialized FLUID that looks like a MOSAIC.

• the plasma membrane is a MOSAIC.

• the fluid mosaic model is NOT related to the plasma membrane.

• a plasma membrane is a MOSAIC of components that move FREELY and FLUIDLY.
