Scientists uncover a new pathway for synthesis of Threonine (see below). They also identify mutants that cannot grow on media lacking threonine (Thr-1, 2 and 3). These mutants have mutations in separate enzymes in this pathway. They are able to grow when different supplements are added to the media (see below). Based on this, what is the order of the enzymes in this pathway? a. Thr-2, 1, 3 b. Thr-2, 3, 1 c. Thr-1, 2, 3 d. Thr-3, 2, 1
