QOTD

In receptor-mediated endocytosis, receptor molecules initially project to the outside of the cell. Where do they end up after endocytosis?

a.On the outside of vesicles

b.On the inside surface of the cell membrane

c.On the inside surface of the vesicle

d.On the outer surface of the nucleus

e.On the ER

Membrane Transport Red Rover

• Create a human membrane

• Other people will act as ions or other molecules

• We will do multiple rounds, beginning with passive transport (osmosis, channel-mediated diffusion, and facilitated diffusion) and then active transport.

Exit Slip

• Complete the Membrane transport quiz
