What do you mean with the functions are being disabled, and the key
bindings don't get responses?

For me, all these functions work and are bound to their usual keys in a
buffer of a tex file.

11.86 is more than five years old, and your Emacs version is quite
dated, too.  Could you please try again with at least a recent AUCTeX
version, e.g., 11.88?
