The Plasma Membrane
By Rachel, Ogechi and Prerana
The Plasma Membrane is made out out of the Phospholipid Bilayer
Embedded into the Phospholipid Bilayer are Channel and Carrier Proteins
I'm Larry the Large molecule. I can't easily diffuse through the bilayer due to my large size, so I use facilitated diffusion.
I attach to the carrier proteins binding site, which causes it to change shape and let me pass through!
I'm Charlie the Charged molecule. I also can't diffuse easily across the membrane because of the non-polar core so I need some help
The channel protein is charged with polar groups, I can pass through with its assistance.
I'm Louis the lipid soluble molecule. As I am soluble in the lipid part of the bilayer, I can easily diffuse across the membrane.
I'm Wayne the Water Soluble molecule. I can't diffuse across the bilayer due to the hydrophobic core, so I use facilitated diffusion.
I am transported via a carrier protein so that I can pass through.
Hi I'm Santa the Small Uncharged Particle!
I can diffuse through the bilayer easily as I'm very small and I'm soluble in the lipid core!
Thankyou for watching!
