A quasar is a type of astronomical object that emits incredibly large amounts of energy and light as a result of material falling into a supermassive black hole at the center of a galaxy.
No, not in the slightest sense. A quasar, pulsar, and galaxy are three very different things.
Scientists have only recently decided that a quasar is a galaxy with a relatively new supermassive black hole that has "recently" formed. This isn't certain, by any means; only a few years ago, there was considerable debate about what, exactly, a quasar was. As small as a star, brighter than a galaxy; nothing seemed to make sense.
I guess that would apply to any galaxy, since stars will have a tendency of accumulating towards the center.
A quasar is a celestial object located at the center of a galaxy, emitting intense radiation and believed to be powered by a supermassive black hole.
Quite a bit more than that. A typical quasar is several times brighter than an entire galaxy that has no quasar.Quite a bit more than that.

A quasar evolves into a galaxy as it exhausts its fuel supply of supermassive black holes at its core. Once the black hole stops accreting matter and emitting large amounts of energy, the quasar phase ends, and it becomes a mature galaxy.

A quasar will have the brightest galactic centre.
The center of the galaxy is located in the constellation Sagittarius. It is known as the Sagittarius A* region and is home to a supermassive black hole.
That must refer to a quasar - however, the claim that it is "a thousand times brighter" is somewhat doubtful. A quasar may seem brighter than it is, (a) because of gravitational lensing, and (b) because the jet is pointed towards us. In any case, a quasar is a small region in a galaxy, which is often brighter than an entire normal galaxy.
