when amino acids react with alcohols, do they produce nh3 as well as esters?

why does na2co3 produce CooNa, i thought it was acidic so would produce nh3+ on the molecule
why does na add to the oh group as well?http://pmt.physicsandmathstutor.com/...y%201%20QP.pdf

NH3 as in ammonia gas? Or NH3+ as in the ammonium ion?

If you esterify using a strong acid catalyst, then it will make the ammonium ion.

Na2CO3 is a basic salt. How can it be an acid? It doesn't contain H, never mind H+! (Yes... I know about Gilbert and his theory).

the mark scheme says that the ester must include nh3+ ion

Yes due to the acidic conditions there is a increase in the [H+] concentration which can accept lone pair of electrons on the nitrogen atom.

does this apply to every reaction that involves a catalyst

If you have a amine and there some form of acid catalyst being used then yeah
