An oxygenase is any enzyme that oxidizes a substrate by transferring the oxygen from molecular oxygen O2 (as in air) to it
https://en.wikipedia.org/wiki/Oxygenase

An oxidase is an enzyme that catalyzes an oxidation-reduction reaction, especially one involving dioxygen (O2) as the electron acceptor. In reactions involving donation of a hydrogen atom, oxygen is reduced to water (H2O) or hydrogen peroxide (H2O2). Some oxidation reactions, such as those involving monoamine oxidase or xanthine oxidase, typically do not involve free molecular oxygen.[1][2]

In brief:

• Oxidases are generally found in cell membranes and are responsible for building of ATP that store cell energy and Oxygenases are responsible for breaking down iron that is distributed to the whole body.

• Oxidases transfer electrons to the molecular oxygen but oxygenase transfers atomic oxygen to the substrate.
