BioKnowledgy 1.4 Membrane transport from Chris Paine (at Dulwich College Shangai) – taken from his fabulous blog BioKnowledgy.
1.4 Membrane Transport notes to complete (created by Ms Green).
A 13m 35s video lesson from Dan Rott:
Some assessment statements are covered in videos by Stephanie Castle.
Click on ‘Cellular Transport’ to see an interactive animation from Wiley that covers diffusion, osmosis, passive transport & active transport. Or here for an animated, narrated tutorial on how molecules move across the cell membrane (from Sinauer Associates).
DIFFUSION
A short, simple animation demonstrating diffusion (from St Olaf) and here are two fantastic animated, narrated tutorials from McGraw Hill Education – how diffusion works & diffusion through cell membranes.
FACILITATED DIFFUSION
Short, simple animations demonstrating facilitated diffusion with a channel protein and with carrier proteins – three types: uniport, symport, & antiport (from St Olaf).
An animated, narrated tutorial on the three types of carrier proteins (from Sinauer Associates).
Or here are is a fantastic animated, narrated tutorial from McGraw Hill Education – how facilitated diffusion works.
OSMOSIS
A short, simple animation demonstrating osmosis (from St Olaf) or here are two fantastic animated, narrated tutorials from McGraw Hill Education – osmosis & how osmosis works.
ACTIVE TRANSPORT
A short, simple animation demonstrating Secondary Active Transport – the Na/K pump coupled with the glucose/Na symport (from St Olaf).
ENDOCYTOSIS & EXOCYTOSIS
A short, simple animation demonstrating phagocytosis (from St Olaf) or here is a fantastic animated, narrated tutorial from McGraw Hill Education – Endocytosis & Exocytosis – which includes a quiz.
And here is an animated, narrated tutorial on vesicle budding & fusing which also includes a quiz (from Sinauer Associates).
Here Paul Andersen gives you a brief introduction to The Cell Membrane.
Mr W’s Cell Membranes rap is good revision as is his Osmosis! rap.
In Crash Course Biology #5 – In Da Club – Membranes & Transport, Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.
