Concept #1: Simple & Facilitated Passive Transport

Practice: The difference between simple and facilitated diffusion is that facilitated diffusion:

Practice: Simple diffusion and facilitated diffusion across a membrane both ___________________:

Concept #2: Kinetics of Passive Transport

Practice: The rate of movement (flux) of a substance X into cells was measured at different concentrations of X to construct the following graph. Does the graph’s data suggest diffusion of X into cells is mediated by a protein transporter?

Practice: The rate of transfer across a membrane is measured for a given molecule. The diffusion rate is seen to be hyperbolic with respect to the concentration of the diffusing molecule. The method of transport is which of the following?
