Mechanisms involved in solute transport across biological membranes
. passive diffusion
. facilitated diffusion
. active transport
. primary active transport
. secondary active transport
Passive Diffusion
. occurs down an electrochemical potential gradient
. three processes: partition from the aqueous to the lipid phase, diffusion across the lipid bilayer, and repartition into the aqueous phase on the opposite side.
Facilitated Diffusion
. across the plasma membrane and facilitated by a membrane transporter.
. form of transporter-mediated membrane that does not require energy input.
. steady state achieved when the electrochemical potentials of a compound on both sides of the membrane are equal.
Active Transport
. requires the input of energy.
. transport of solutes against their electrochemical gradients
. leads to the concentration of solutes on one side of the membrane and the creation of potential energy in the formed electrochemical gradient.
