Studying the symbiosis between the accretion disk, the bipolar outflows and the supermassive black hole from the center of an active galactic nucleus, one can infer the size of the base of the jet. The jet is anchored at the boundary layer of the accretion disk extracting mass, energy and angular momentum from the innermost region of the disk. This has dramatic effects on the emission processes from the disk: the UV spectrum from the disk driving the jet is cut at higher photon energies. That means, the energy density of the UV photons from a disk with jet is much smaller. The equations of the mass and energy conservation are properly analyzed in the context of the existing symbiosis in AGN. Since there are models explaining the TeV γ-ray emission from blazars and quasar, as UV photons upscattered via the inverse Compton effect by very high energy electrons, we address the problem of the external Compton scattering mechanism for different AGN. .
