how do they function in a circuit?
is this correct:
the NPN 'eats' a small current through the base, so that a large current can pass through the emitter and collector or is that the PNP transistor that has that function?

Both types of transistors work the same. A small current into the base will control a larger current through the collector. The difference is polarity, for an NPN, the current to the base and collector is positive. For a PNP the current to the base and collector is negative.

the backside emitter junction ought to be forward biased as a manner to prepare the transistor on. this implies the backside modern-day ought to be into an NPN transistor and out of the backside on the PNP.

Both do that. All bipolar junction transistors do that.
The main difference between the two is the direction of current flow.
