Explanation / Answer

activation gate or activation process: voltage-sensing mechnism, determine how long the channel is open,  ligand- gated mechanism

inactivation gate or inactivation process: helix movement results from changes in membrane polarization, ,binding site for this gate appear after channel has opened

neither:determine selectivity of channel,positively charged transmembrane helix
