If protein A has a channel/tunnel and protein B has a binding site, transport protein A while transport protein B .
- transports solute across cell membranes by active transport .... transports solute by passive transport
- participates in osmosis ..... moves solute from high to low solute concentration
- allows solute to travel up the concentration gradient across the cell membrane .... allows solute to pass passively down the concentration gradient
- obtains energy for solute transport from ATP .... does not require energy for transport of solute
- transports solute across cell membranes by facilitated diffusion .... transports solute up the concentration gradient by active transport
