No, you have to call it explicitly.

public class BaseGlobal : HttpApplication
{
void Application_Start(object sender, EventAgrs e)
{
// Set breakpoint string abc = "";
}
}

public class MyGlobal : BaseGlobal
{
void Application_Start(object sender, EventAgrs e)
{
// Set breakpoint string dddd = "";
BaseGlobal.Application_Start()
}
}
