When I wired an addition to our house some 40 or so years ago,
one of my circuits from the service box started in Romex,
converted to steel conduit, and then back to Romex. Since the
grounding connections were properly bonded to each other, the
building inspector in Los Gatos, CA approved it.
The principle reason for the grounding conductor (green wire) is
to cause the circuit breaker to open if one of the hot wires
shorts to the case of the electrical equipment. If the case just
floated, it would be a shock hazard for anyone who touched it
and also touched something that was grounded.

It depends on the building code used by local jurisdiction. In
many jurisdictions, it IS legal to use conduit as the green
wire IF it is continuous and all the connections are made
properly. As I recall, it's legal in Chicago, where steel
conduit is used for almost everything, in large part to keep
union electricians working.
In other jurisdictions, or if the conduit is not properly
bonded for the entire length, a dedicated green wire must be run.
