Sure.  Use visudo to edit /etc/sudoers and set:
root    ALL = (ALL) ALL
wheel   ALL = (ALL) ALL

If NOPASSWD is in there, take it out.

man (5) sudoers

Sudo doesn't ask for *root*'s password.  It asks for *your* password.  If 
you knew root's password, you wouldn't need to use sudo.  You could use su.
