Cell Membrane Transport

What type of transport do ionophores mediate?

What molecules occur in higher concentrations outside the cell?

What molecules occur in higher concentrations inside the cell?

forms a hydrophobic exterior coating on a naturally hydrophilic molecule and makes it lipid soluble

form ion-permeable channels in membrane and enable otherwise non-soluble hydrophilic molecule soluble

an example of a channel former

an example of a mobile ion carrier

What limits the maximum rate of facilitated diffusion?

Most common example of primary active transport

Do symporters use ATP?

Osmotic pressure is attributed to...?

-similar to facilitated diffusion
- rate limited by v_max of the transporters
