How to store membrane vesicles without losing activity of any constituents?

Describe what gap junction are, emphasizing on how they are different two other cellular points of contact, their protein components and cellular function. Describe the three main sources of membrane fluidity.  Describe in detail what proteoglycans are, including their hygroscopicity and biological roles.

Match the following statement related to membrane transport processes to the appropriate term or terms: passive transport, facilitated transport, active transport. A transporter (or carrier) protein is necessary. (Select all that apply.) passive transport facilitated transport active transport O O

how can you increase the rate of facilitated diffusion across the plasma membrane?

I think it works by freezing the bilayer of the membrane and then hitting it sharply with a diamond knife. The sharp hit creates a fracture in the membrane and usually that fracture follows the plane between the two layers of the membrane lipid.
