Do electrons emit real quarks when dropping between energy levels?

[Pakbabydoll]

Quarks are smaller then electrons?
I read that when a electron moves from a higher energy level orbit to a lower energy level orbit it emits a "real" quark... So are other quarks virtual?

An electron emits a photon when transitions between energy levels. A virtual photon is a force carrier for the electromagnetic field.
