I think it's the same in Mandarin, but the question structure also includes both forms, e.g. 'this cake you want not want?'--'want'.
Perhaps I misread though, I thought you were saying the verb 'want' is used in all cases, I was just saying my understanding is that it would be used when that was the verb in the question, but for 'do you go' similarly 'go' is used in the answer.
