Query: The Black Hole- Bulge Relations in Active Galactic Nuclei   We show that Massive Black Holes of AGNs follow the same approximately linear
relation with the luminosity of the host spheroid (bulge) found in normal
(quiescent) galaxies, with the black hole mass being ~0.002 that of the bulge.
We also demonstrate that Narrow line AGNs seem to have a significantly lower
Mbh/Lbulge ratio, which implies a new strong correlation between Mbh/Lbulge and
the width of the broad emission lines of AGNs. Combining existing data, new
observations and extrapolation schemes based on the Faber-Jackson relation, the
relation between the BH mass and the stellar velocity dispersion in the host
bulge of AGNs is constructed. It too agrees with the relation found in
quiescent galaxies.
