AK too weak on the turn?

[Chobohoya]

Hi, I just played this hand a little while ago in the 5/10 6-max on party. The main opponent in this hand seems to be a calling station, loose and passive, which is what slowed me down when he woke up raising on the flop. Should I bet this turn regardless? If raised, do I call down unimproved? Looking for opinions, thanks.
