As we bent and moved the structure, the membrane stayed intact and moved fluidly.

The cell membrane can repair small breaks in the bilayer. As we pushed our fingers through the film, the membrane stayed intact without breaking.

As we blew bubbles through the straw and exchanged air it demonstrated how gap junctions let small molecules and signals pass directly between cells.

The bubble split in two when we pulled the thread in the middle.

1. Active transport: movement of substances across a membrane, often requiring energy.

2. Facilitated Diffusion: a process of molecules through a hydrophilic channel or with the help of a transporter protein.

3. Channels and pumps: Specific membrane proteins that allow for the passage of ions or molecules. 

Signal transduction: Receptors and GPCRs

Various Enzymatic Activity

4. Cell recognition: Glycoproteins and markers
